in my area DOM calculations have changed dramatically in the past month. Check your Sunday paper for transfers and check those out. Realtors relist properties to "refresh" them and don't always add those DOM up.
if you buy property and do the work yourself you risk losing $$$ because you don't have the speed you need to turn the house. I know a perfectly lovely house that threw up a "Rent to Buy" sign because the house won't sell. The reason it won't sell is that the kitchen and bathroom remodeling looks amateurish, ie not professional If you get enough money to sub out the work you can move the house along and control it's marketability much better. Insurance companies are nosey about what licensed contractor worked on the property before they up the insured value of a remodeled house.
I think living in a house and remodeling it slowly makes more sense because you can afford to hold the house, stage it and if you only make a marginal profit at least it's tax free after two years.
In my area, realtors are hugging prospective buyers because they are so rare. Things are a little tough right now.
