A couple things to keep in mind:
- In this market, to sell quickly, you need to have a house that is at the top of the range in terms of condition, and the bottom of the range in terms of price, compared to competing homes in the area.
- To accomplish the first half of this equation (top of the range in terms of condition), you need to be intimately familiar with competing homes on the market, and you need to do a rehab at least to that level, and preferably a notch or two higher (as Harrison pointed out).
- To accomplish the second half of the equation (bottom of the range in terms of price), you need to be buying very, very inexpensively. It can be difficult to have the nicest house at the lowest price and still make a profit, but it's definitely doable if you're selective.
- Sometimes, in order to stick out above your competition, all it takes is great staging. Two equivalent houses -- one empty and one nicely staged -- are not equivalent at all; the staged house will sell much, much faster, and sometimes at a higher price. So, if you can't afford to differentiate based on finishes, consider staging to serve the same purpose.
- To Aly's question, decide on your level of rehab before you consider cost. Know your competition, and know what you need to do to move your house faster. Once you know what you need to do, THEN figure out the cost and determine if you have a potential deal or not. If you try to back into the deal (determine your budget first and then figure out what you can do with that budget), you'll find that you're talking yourself into deal that aren't really there.
- In terms of building a budget, start with the materials. These are fixed costs that -- if you're working on the same types of houses over and over -- can be priced out ahead of time and will never change. For example, I know that the price for each bedroom fan/light I buy is always $17.64. So, if I walk into a house with 3 bedrooms, I automatically know that I'll be spending $52.92 on fan/lights for the bedrooms. If you price out all your materials upfront, you can figure out your materials cost for a house in about 5 minutes this way.
- As for labor costs, it will take a little while to figure that out, but once you start using the same contractors over and over, your labor costs will become just as obvious as your materials costs.
Hope that helps...
