When the boiler in one of your rental properties breaks down, usually in the middle of winter, it is likely to be an expensive headache you could have done without. Your tenants will be unhappy at the interruption to their central heating and hot water supply, plus you have a nice big repair bill to look forward to.

Unfortunately, boiler breakdowns are becoming an increasingly vexing problem, and not just for landlords. In the good old days, back boilers were the most common type of boiler and as long as they were serviced regularly, they went rarely went wrong, but even if they DID go wrong, the repair costs were minimal. However, times have changed and these days we are positively encouraged to invest in new combination and condensing boilers when the time comes to retire old faithful in the kitchen.

The new style of condensing and combination boilers are supposed to be more reliable and efficient, but based on breakdown statistics, this is apparently not the case, and because of this an increasing number of people, including many letting agents in the UK, are calling for the government to force manufacturers to provide 10-year guarantees on their boilers.

I know from my own experience how unreliable a modern boiler can be—I was forced to invest in a new boiler a few years ago and within two years it had broken down more times than I care to mention and cost me a fortune in repairs. In the end, I replaced it with another new one, which was an expense I didn’t exactly need at the time. Imagine if the same thing happened in several of your rental properties: your profits would be annihilated overnight! So if you have had a bad experience with one particular boiler manufacturer, spread the word and warn other landlords.

With the start of the London Olympic Games just a few short weeks away, landlords with buy to let in the London area are frantically marketing their properties in the hope of attracting short-term tenants for the summer, and with some properties advertised at more than £6k per week, the potential for raking in a huge profit is massive. But what about those properties where tenants are already in residence?

Sadly the lure of a quick profit is proving too much to ignore for some unscrupulous private landlords. Instead of treating their existing tenants fairly, these landlords are serving hurried eviction notices telling tenants to pack their bags and get out or face having their rents increased to unaffordable levels.

Can private landlords do this?

Evicting tenants without giving them sufficient notice is illegal, so the answer is a resounding “no”. It is also illegal to harass a tenant in order to provoke them into leaving a property and should a landlord be found guilty of such offences, they face prosecution and a custodial sentence at Her Majesty’s pleasure.

So instead of being seduced by short-term profits, look at the bigger picture and recognise the benefits of keeping reliable long-term tenants who pay their rent on time and don’t trash the place. It might seem like easy money to let your flat or house for the duration of the Olympics, but when the Games are over and everyone has gone home, you may find it impossible to find new tenants as a glut of rental properties comes on to the open market once again.

The rising demand for rental accommodation combined with a cap on benefits is slowly turning parts of London into a third world ghetto. According to a story I read in the Guardian, greedy landlords are exploiting the demand for accommodation and renting out illegally converted sheds and outhouses, very often to illegal immigrants, and it is not unusual for landlords to charge hundreds of pounds per week for a section of floor space in an overcrowded house with too few bathrooms, no fire alarms, dodgy wiring, and with resident rats and cockroaches to boot.

Can you imagine living in a converted shed with no hot water or insulation, in the middle of winter? No, nor can I, but increasing numbers of tenants are being forced into renting rooms and hastily converted outbuildings to avoid living on the streets and council planning enforcement inspectors are getting used to finding tenants living in overcrowded conditions or spaces so small even your dog would object.

It might seem difficult to understand why people would choose to live under such conditions, but when all you can afford is a mattress on the floor of some squalid house in one of the cheaper boroughs of London, choice probably doesn’t come into it. But on the other side of the coin are the landlords who trade in human misery, cashing in on the plight of so many vulnerable and desperate people, many of whom are in no position to make complaints about their living conditions.

So if you are picturing a 19th century slum, you’re in the right era, but sadly this unhappy state of affairs is unlikely to improve any time soon.

Squatters are every landlord’s worst nightmare, which is why void periods between tenants, or down periods when a property is undergoing essential renovations are particularly risky times when extra security is essential.

Up until now, squatting was only ever a civil offence, so if you were unlucky enough to end up with squatters taking up residence in one of your properties, you were probably faced with a devil of a task trying to have them evicted. But thankfully changes are now going ahead and despite a few hiccups along the way, new legislation making squatting a criminal offence is set to come into force in September, a move which should be welcomed by landlords everywhere.

Homeless charities are against the move because they say there are already large numbers of homeless people forced to live on the streets because of legal sanctions used to deter squatters and in their view, criminalizing squatting will simply make the problem worse.

But as many of us already know to our cost, squatters can cause a massive amount of damage and once they are in situ, it is very difficult to get rid of them. To try and curb this problem, squatters now face a maximum £5,000 fine and up to 6 months in prison if they are found guilty of taking up residence in a property illegally.

Hopefully the severity of such measures will prove to be a deterrent for all but the most hardened squatters, but it is still very important that you try and avoid leaving a property empty where possible, and if you have no choice, always make sure you have effective security measures in place.

You may remember I talked recently about future problems obtaining insurance for properties in flood risk areas: insurance companies are threatening to withdraw all buildings and contents insurance policies for any properties in areas susceptible to flooding, which applies to a fairly large number of properties in the UK. So with flood water levels creeping upwards in the wake of the recent high rainfall across much of the UK, what is the latest news on the matter?

Insurance companies and government ministers have still not reached a mutually satisfying agreement and the arguments rumble on. As things stand, the insurance companies are planning on withdrawing insurance cover from July onwards unless the government agrees to pledge funds towards new flood defences in known risk areas.

Unfortunately, government funded flood defence plans are now under threat thanks to the purse tightening measures in place right now, so unless an agreement is hammered out between the two sides, landlords with properties in flood risk areas could have their insurance policies withdrawn or be forced to pay astronomical premiums to continue their cover.

Without insurance cover in place, many landlords may find that they are in breech of their mortgage conditions and unable to secure any new loans on the property. It will also be impossible to sell such properties since prospective buyers are likely to be non-existent. As a consequence, there is a great deal of concern amongst industry insiders that the issue could potentially destabilise the housing market in some areas, which would be highly undesirable for everyone.

As the number of people moving from owner occupied properties into rental homes increases, so too does the number of people moving their pets along at the same time. Unfortunately, a lot of landlords explicitly forbid pets in their properties because of the damage they can cause, so many tenants don’t bother telling the landlord and simply take their pet with them in the hope the landlord won’t notice.

How can you prevent pet-related damage to your properties?

The only way to protect your properties is to be extra vigilant when inspecting them part way through a tenancy. If you do not allow pets, you will have to be on the lookout for any signs of pets living at the property to be certain your tenant is not hiding a menagerie from view.

The first, and sometimes most obvious, sign of pets in residence is the odour. Cats and dogs often leave pungent smells, from pet urine to eau de smelly dog, so if you catch a whiff of anything suspicious when you walk into the property, it is a good idea to start asking some questions.

Other tell-tale signs to look out for include:

 Damaged carpets around doors

 Scratch marks on doors and furniture

 Pet hair on carpets and soft furnishings—check under cushions and along the perimeter of carpets where hair accumulates and is not picked up by vacuum cleaners

 Yellow patches on grass where pets have urinated

If you DO find evidence of pets in situ, you need to address the issue fast as pets can cause a huge amount of damage to furniture and carpets, which often costs hundreds of pounds to put right.

With the population of Liverpool on the cusp of the first “chosen by voters” mayoral election, campaigners against rogue landlords have come out in force to try and persuade the soon-to-be elected mayor to deal with what is becoming an ever increasing problem in the city.

The national housing charity, Shelter, set up a spoof lettings agency called “Rotten Homes” and invited local people to come and sign their petition against rogue landlords in Liverpool. Unsurprisingly, along with a large number of signatures, there were plenty of colourful stories, too.

I thought I’d heard it all over the years, but even I was shocked to read the tale of a young tenant who went on holiday, only to return to discover her kitchen had been ripped out and the landlord wanted fifty pounds to put another one in. She had to endure living with no appliances, worktops or a floor for three months before she chose to vacate the property. And if that sounds farfetched, how about the story of the landlord who regularly sent his relatives around to deliver threats to the tenants who were living in his properties!

Personally I find it a pretty sad indictment of today’s society that so many landlords are ready to take advantage of the those who have no alternative but to live in rented accommodation. Operating rental properties is a business and landlords have a duty of care to make their properties safe and habitable for tenants. But with 43% of rental properties classed as below par in Liverpool, it would seem that a lot of landlords are not fulfilling their obligations.

Millions of people are self employed these days: according to HM Revenue, the current figures show more than 14% of the working population run a small business from home. With the job market so volatile and employment opportunities scarce, running a business from home is the answer to many people’s financial woes; it is also an excellent way to generate additional income on top of a full-time wage earned elsewhere.

But although running a home business is definitely not illegal, landlords do need to be aware of the legal implications to themselves should any of their tenants be operating a small business from one of their rental properties.

In order to run a business from home, the owner of the property needs to give their permission, and in the case of larger businesses, for example an extensive online retail store, the property owner may have a responsibility to apply for planning permission.

If the property is mortgaged, it is possible that running a small business from the property breaches the terms of the loan; buildings insurance policies may also be voided as a consequence.

And if the tenant uses the property address to register a small business, which subsequently runs into financial difficulties, you the landlord could end up suffering all kinds of woes with credit reference agencies.

What should I do if my tenant is running a business from home?

Ask them to cease trading immediately, and if this fails, give them notice to quit the property and inspect it to check for damage or alterations.

As any landlord knows, the rental market has increased phenomenally over the last few years as more and more people choose to rent rather than buy their home. But is this trend a temporary one, or will the number of people renting as opposed to buying continue to rise over the next few years?

Research from UK estate agents and property websites seems to suggest that the trend is not a temporary one and current estimates indicate that by 2016, around one in five homes will be rented in the private sector instead of owner-occupied. Unfortunately, there are not enough rental homes available to meet the demand, so unless a further 1.1 million homes are added to the pool of available buy to let properties, there is likely to be a massive shortage, and as I learnt in my Economics class in school many moons ago, when demand outstrips supply, prices go up.

Current figures show that around 27% of homes in London are now let in the private sector (which has overtaken the social housing sector for the first time). The average rent rose by 5.2% across the UK last year and landlords in the buy to let sector earned approximately £48 billion in rent in 2011, a figure which is expected to nearly double over the next five years.

This is obviously good news for landlords looking to invest further in the buy to let market, so if you are still on the fence, now would be a good time to consider whether buy to let is the right move for you.

According to recent figures, the average rent in some areas, particularly in London, is rising much faster than tenants’ incomes, which could spell bad news for landlords in the worst hit areas. Rents across the UK rose by 2.6% last month whereas incomes fell by 1.2%.

How are these changes affecting UK landlords?

These changes are affecting the buy to let market in a number of ways: more tenants are choosing to share accommodation as a way of saving money whereas others are moving away from the more expensive areas in an attempt to find cheaper accommodation elsewhere.

However, affordability in the buy to let sector does vary across different areas of the UK. In Wales, the North West and North East, the average rent has fallen slightly over the last month, but everywhere else rents continue to rise. In the long term this will cause problems with increasing numbers of tenants defaulting on their rental payments, which is not good for landlords.

Cuts in housing benefits are also exacerbating the problem and a survey by the NLA has found that many landlords are choosing not to rent their properties to tenants in receipt of Housing Benefits because the payments no longer comes close to covering the rent. These changes will inevitably force many tenants on benefits into shared accommodation, as they won’t be able to afford a flat or house. Because of the cuts, around 53% of landlords surveyed said they would no longer be letting properties to tenants on benefits by 2015.

Are you one of them?
