The buy-to-let sector has emerged as one of the few sound areas for investment in the current political and economic climate.

With demand among prospective tenants high, house prices seemingly unaffordable for the majority and saving for a deposit nothing but a dream for many, landlords have been able to benefit from the rising rent prices that have resulted.

And despite the stamp duty holiday helping to facilitate a spell of increased buyer activity, LSL Property Services' Buy-to-Let Index for April has revealed that the average rent in England and Wales is back on the up - rising for the first time in three months by 0.5 per cent.

"First-time buyers now must save for longer to pay for stamp duty - in addition to finding substantial deposits - making house purchase a more distant prospect for many tenants," said David Newnes, director for LSL Property Services.

"As a result, tenant demand will only strengthen, providing impetus for rental inflation in the long-term."

Considering what seems to be the strong potential for the buy-to-let sector to continue growing in the coming months, investors are likely to cash in on the higher prices, and landlord insurance policies will be important to keeping assets profitable in the wake of any unexpected damage.

Yet while rent charges rise, online letting agent Upad has advised landlords to focus on letting to reliable, long-term tenants rather than hiking their prices for a brief period in a bid to squeeze the most out of the market.

"A landlord shouldn't put their rents up by ten per cent just because that is what was in the papers at the weekend. They need to understand their marketplace," said James Davis, chief executive officer at Upad.

If demand for rented accommodation intensifies, it seems that the only way is up for the nation's rent prices.
