Many rookie real estate investors make the mistake of overpricing their properties when all the work is done. The bottom line: If you want a successful listing that produces multiple offers, you must price your property correctly. Additionally, an overpriced investment property will sit on the market too long and tie up your money. The tried and true method for pricing your flips correctly is to find reliable comps in your property's neighborhood--and the best way to do that is to work with a Realtor(R). You can also check the market yourself periodically, while you're fixing up the property.
