I don't believe that a properly worded letter of intent will be a legal issue; it is just a matter of reputation, and basically doing business transparently and honestly.  

I care about my reputation and my REI Students.The bust from the CFPB - not underwriting the Buyer on a seller financed deal - is 36 monthly payments, down payment, lawyers costs, courts.1% fee from the RMLO to look at a 1003 app and give an opinion is basically a cost to do business in the USA on Rent to Own.Many will not agree with me.But I would rather have me and my home seller protected.

Keep in mind, their reputation is on the line, too! 

So, on that front, can't say, but there is also your reputation, you can trash that before you get started too.Moral of WH, explain up front to an owner as to what you are doing, they are to be fully informed, use an option if you can, not a contract with mickey mouse exits as the con artists do it.

You can pay with financed cash without putting a financing contingency on the purchase contract, but you risk your earnest money and your reputation as an investor who can close a deal if something goes wrong with your funding source. 

Sorry for the bad grammar. ..Just shocked that wholesalers have a bad reputation.

Does anyone know a reputable commercial builder in Atlanta?

If you have a great relationship and reputation you can get more than 100% financing, but it isn't common.

Newbie investor with a rental property in atlanta metro area.Any views of the area appreciated.Looking for advice on reputable property attorney.

Doing things that give you a bad reputation won't ever be a benefit toward a successful business.Not everything is excepted everywhere, do what is customary in your area is my advice. :)
