Working with contractors can be extremely difficult as projects get delayed and there is poor communication(red flags were not present before project began).

Having "real estate investing" or "real estate" anything, in your LLC name will surely raise red flags for banks, especially as you move beyond net 30 accounts to larger credit lines.

Next, I would find out who the attorney(s) is in your area that is known for regularly dealing with the Zoning Board.

Although not tragic, still a small red flag - ok so 24,800 leads to go.While taking a break from the email task, I came across this BP thread - WOW! 

Navigating NYC's zoning regulations can be complex @Jon Pflueger, especially in M1-2 districts, which are primarily designated for light manufacturing and commercial uses.

Due to the geographical factors that make Reno/Sparks fairly locked in, and the lack of multifamily zoning in Reno. 

This is a red flag for the IRS.

In the case of a single family home house hack, say a single level ranch with a daylight basement - it lives and functions kind of like an up-down duplex, but the zoning and property type is 1 unit SFR.

That first step is to get you outside your comfort zone so you can network and get help.

I would suggest you talk to a mortgage broker or a bank though - if those homes are zoned commercial you will probably have a hard time getting an FHA or low down Conventional mortgage.
