Its only simple when you know how!

Remember, if you are buying with a mortgage, rent-to-property price yield will not be the return you get.

To work out your annual return on investment subtract your annual mortgage cost from your annual rent and then work this sum out as a percentage of the deposit you put down.

For a £100,000 property that could rent for £500 per month, you would need a £25k deposit and roughly £2,000 in buying costs.

£75k mortgage at 5% interest rate = £312.50

£500 rental income x 12 = £6,000

Difference = £2,250

Deposit + buying costs = £27k

Annual return = 8.3%

Don\'t forget tax, maintenance costs and other landlord expenses will eat into that return.
