RENTERS: NEVER AGAIN LIKE THIS LAST TIME

My nephew bought a brand new house, then got married and moved into his new wife's new house. Couldn't get his sold, so finally let it go on a lease/option. After about a year, had to take them to court to get them evicted for past rent. They tore it up so bad, he had to spend a bunch of money on it, to sell it at a loss. Now he wants me to go in with him, building duplexes to rent. I'd rather build them to sell.
