The first one was 15% ( Mortgage Express) .the second 20%.( Legal & General). The mortgage on the first was about £450 a month, it is now just over £300. so the rent of £750 returns a profit. We didn't necessarily intend them to be profit making as long as they are self funding and the property goes up in value, Here in St Albans, there is no doubt it will. We paid £165,00 for our house 5 years ago, it is now worth £500,000+ A two bedroom terrace stater home costs in the region of £165,000. A two bedroom does n't get a lot more rent than a one bed, not enough to justify the extra cost of purchasing.
We would advise, buy new if you can, you tend to get integrated appliances, (a hob, oven , waste disposal and a washer drier with our new one) don't buy a ground floor if a flat, within walking distance of a mainline station - a mile or so, and let it unfurnished. A good quality carpet, like a neutral berber throughout, and plain curtains. Make sure it has a god size bedroom, room enough for a double bed, check for built in cupboard space.
The estate agents so got to know us and now they ring us as soon as something comes on the market, we know what we are looking for. and we would buy any flat in the complex of the first one we bought, unseen, as there is so much demand. Get yourself onto the management committee as well!
We have an extremely good letting agent (10%) totally managed, they vet tenants, collect the rent and guarantee the rent if the tenant defaults. We have a London doctor in our first, and they have a tenant lined up for the next ready to move in on completion day!
Happy to answer any other questions, as we took a long time to get round to doing it, now we aim to buy one a year.
