For some time landlords have invested in additional properties merely for that purpose, yet it seems like since the nineties the demands for rental property have dramatically increased in mortgage firms, hoping to exploit amateur landlords.
However, the recent economic situation has meant a decrease in house prices so the property market is one industry that is merely scraping by at the moment. House prices have dropped rapidly and rents have gone down too. Many landlords and property agents have gone bust. In a nutshell, buy-to-let investors are finding themselves unable to make profit because rents are lower than the price of the mortgage.
So if you are thinking of getting into the buy-to-let market, you'll have to tread carefully. Make sure you do your research and know your stuff. If you have the cash to spare, now is actually a good time to strike while the iron's still hot and buy houses at cut prices - with house prices down you're sure to score a good deal!
Analysing trends, researching history, and documenting successes and failures in buy-to-let situations is mandatory. Like any business there is a correct protocol that increases the chances of monetary success: the right ideologies, the right contacts, the key-markets, and surely the right steps to initiate the process.
With a bit of good luck on your side, you could very well make yourself rich. But don't go into this deluded: you'll have to do a lot of hard graft and be business savvy in order to succeed in this market. It definitely sounds easier than it really is to make a profit out of it, especially at the moment.
