A few scenarios come to my mind:- After a successful close of sale, a small gift to show good faith/marketing such as a $50 gift card to Home Depot?

@Kay Faith many when I bought my first property I ran my numbers the exact same way.

All contracts, options, or other devices not based upon a substantial consideration, or that are otherwise employed to permit an unlicensed person to sell, lease, or let real estate, the beneficial title to which has not, in good faith, passed to such party for a substantial consideration, are hereby declared void and ineffective in all cases, suits, or proceedings had or taken under this chapter; however, this section shall not apply to irrevocable gifts, to unconditional contracts to purchase, or to options based upon a substantial consideration actually paid and not subject to any agreements to return or right of return reserved.

General consensus is rehab will cost more than you think, take longer than you think, and ARV might not be as high than you think.All that to say, you eventually have to take a leap of faith.

I have zero faith in single family or condo's cash flowing in an appreciating market (which I believe was your original question). 

I have withheld his entire deposit.First, he is stating we didn't tell him of his right to an initial inspection and that's bad faith.

Start developing one now.If your tenant moves out, the law requires you to make a "good faith effort" to find a new renter.

The majority of the title companies in the area won't touch title assignments due to the perceived risk on their end of a bad faith transaction. 

I worked as a Construction Manager for GC's for 15 years between New York City and Miami, and last year I took the leap of faith of becoming a Real Estate Developer here in Mexico.2.

It's all or nothing (at least in my market).I generally don't bundle utilities with my S8 rentals because I just don't have faith in tenants not to abuse it if I did.
