Demand for housing in the private rental sector may well be high at the moment, but landlords still need to ensure their properties are appealing to tenants if they want to avoid costly void periods and set the maximum rent prices.

So as owners decide whether it's going to be more cost effective to fit a quirky new kitchen, shell out for brash colours to be slapped on the walls or invest in traditional wooding flooring to make their assets as attractive as possible, one expert explains that keeping things simple is the safest bet.

"The rule is to keep the property neutral," says Lee Grandin, director at Landlord Mortgages. "Do not over furnish a newly purchased buy-to-let. Some landlords will wait for a potential tenant's wish list and then furnish according to the chosen tenants needs."

Considering that we're not all interior design experts with an in-depth knowledge of the latest trends and fashion when it comes to decorating, ensuring that your property's aesthetics are subtle and accessible is going to be a better idea than taking risks with vivid colours and oddly placed mirrors - and it's also going to be cheaper.

And this could be particularly helpful for the 60 per cent of landlords who Mortgages for Business revealed are planning on expanding their portfolios in the next six months.

According to the organisation's latest survey, investor confidence in the buy-to-let sector looks set to remain strong, and 84 per cent of those who are looking to purchase more properties are said to be searching for residential-style letting opportunities.

Indeed, given that demand for rental accommodation does not seem to be showing any signs of waning in the near future, now appears as good a time as any to invest in further properties, and these can protected against unexpected costs with effective landlord insurance policies.
