As a former flipper of houses in the upstate NY area, I gotta agree with Mesh and Herb. Be very careful. This kind of venture can easily financially ruin you. First off, if you are trying to get an FHA mortgage, you can forget the fixer upper. They won't touch it. They send their own inspectors and if the paint is peeling, they want the entire house repainted before theyll approve the loan. So you can just imagine what they'll look for inside an older home.
My advice would be to find a "dated" home. These are usually owned by older folks who have kept up maintaining the home, but just haven't updated the kitchen, bathrooms, floor coverings. The bones are good, but the skin ain't tight.
These can be good bargains, and you can do the updating as you go and still have a liveable house. There's gotta be hundreds of these in Florida.
Investment wise, you'll get most of the money back if you sell the house down the road. On a real fixer upper, where we are talking stripping walls to the bones, wiring, plumbing, hvac, drywall, plus all the new fixtures and floorings, you're not likely to see a return on that money and more likely a loss, depending on how cheap you're able to buy the property for.
Also, when it comes to budgeting, take your worse case scenario and add 30%. You'll be lucky if you stay under. Like others have said, when it comes to older homes, if you're using a contractor they have building codes they have to adhere to, and permits to obtain which means inspectors to satisfy. It can turn into a snowball of cash that just keeps growing til it's cheaper to hire an arsonist.
I flipped close to 35 houses from 2000 to 2009 when the market fell out. Lots of guys around here thought it looked easy and tried it. HGTV should make a show that has nothing but all the problems that do it yourselfers run into while trying home remodeling projects. That would be fun to watch for me, but I'm a little twisted like that.
