Build out the network for GCs in your area and start to bid jobs, then you can build out how much each job would cost.

Working to systemize this business to run efficiently with future limited supervision to then take the cashflow/profits to continue investing in building our long term rental portfolio as well as invest in other business endeavors.

If the deal does not pencil, then don't do it. 

Second- these developments where the same person develops, builds, and then requires you to use them for management- they always suck.

I know there's seller finance and "B" lender that are good for the short term, but if a balloon payment is due say in 5 years, there's no guarantee that my DTI would be in a better place then I'd be stuck without funding. 

Or find a deal first then market it to buyers, then offer on the house and create an agreement with the seller & buyer?

Then level the floor - really shouldn't need more supports after the first if they were installed correctly.

Quote from @Denver McClure: Hey @Buck Dabill, if AirDNA isn't giving you quality data, then I would suggest manually scrapping similar properties on the lake via Airbnb, VRBO, and Vacasa.

@David Robert - Based on what you're saying it sounds like certain sections of drywall/wall are better off coming out and replacing then trying to repair.

Let us say you want to have a Section 8 rental, then first try to define what you can afford and where is that money will come from.
