With the scheme I am looking at, you can buy any house. The man from the scheme has basically told me to go away and find a house. I've to put him in touch with the seller and he will negotiate the final details. He said not all sellers will go for it, but round here, houses can be on the market for years, and there are quite a few people who end up renting against their will because nobody has the money to buy, at least this way they would be getting an income and eventually a buyer. Lots of properties with no upward chain round here as well.
I wouldn't like a new build tbh.
It just seems daft to move in a couple of months to rented, and then again in one to three years (depending on how quickly we save up) and all that time have the risk of being evicted on the landlords whim.
We would be buying (and renting in the meantime) at market rates, although our rent would have some on top to pay into our deposit.
Houses we are looking at start at £65,000 needing renovations and go up to about £120,000 for a newly modernised property. There was one new build, but it was a barrat box with a postage stamp garden and much more expensive than the nice solid ex council houses we were looking at for half the price. We would need a deposit of 3% of the property value to move in and begin the renting part, then 15% to buy it.
We did consider buying the house we are renting now, but it is only two bedrooms and ideally we would like a spare room that we could put one of the kids in as they get older.
