This has reaped huge rewards for some of my clients. Don't just take their word for what your home is worth. Consider renting out the garage or your basement or that extra bedroom. Consider renting out the whole dang house. Nevermind, forget I asked.
Renters can simply move to a cheaper place.
Or, you could offer to do maintenance on the property in exchange for a portion of or all of the rent. The same goes for home improvements. It may not even be on the property you live in. Many landlords own several pieces of property and could use the cheap help rather than pay professionals to do the work. I'm not talking Single White Female types here.
