Yes, having a bank could potentially help with the financing of the homes. However, (and please take this politely), whoever told you that "finding a lender for the homes in MS is tough" is a moron. 100%, absolutely NOT the case. I'm working with at least 8 national lenders for the homes we are selling in Gulfport-Biloxi right now. Lending always comes down to what and whom, not where...Owner Occupied/Investment home, Full doc/Stated doc, Loan to value/appraised value. The ONLY time a developer has trouble getting financing is when they "sell it wrong to begin with." If you promise your people 100% LTV and only 95% exist, that's a problem. If you tell them that they are getting 10% cash back at closing and the lender only allows 3%, that's a problem.
Sorry to sound like a no it all (which I'm afraid I can come off as sometimes), but working with developers to acquire/front end finance/entitle/land plan/market/pre-sell/back end finance is how I feed my family. And it's a ton of fun even if the developers a moron. They just need to listen to the folks that know what they are doing.
