I would definitely establish some clear cut boundaries with the tenant and make sure that she understands that it is above and beyond your responsibilities and I would not make it a habit with future tenants.

I also figured it would cut down on closing costs, and I could use my commission to put towards my down payment.

other than for rental purposes we are cutting way back on flipping for retail.we are concentrating on ground up.. less competition more certainty in cost to build.I am done tearing into a 100 year old house only to discover bad things.

I'm thinking I should create a C Corporation instead of an LLC, since the corporate tax rate was lowered to a flat 21 percent rate this year since the passage  of the Tax Cuts and Jobs Act on December 20, 2017 to avoid paying UBIT tax.

So here we missed one payment in this example, but our credit report actually shows 3x30 day lates.Like @Harjeet Bhatti said, you're probably cut off from the gov't subsidized Fannie/Freddie stuff for an investment property for a year or so.However if you come across something, and it's such a screaming deal at that price that it still makes sense even with non-ideal financing (remember that if you have to choose between the two, killer price is better than killer rate -- as any successful flipper will attest to), there's a lot of "Alt-A" (once upon a time called "sub prime") that's come out just in the last year that's better than HML.

With all useable land and fertile land(With the exception of Grand Oaks which cannot be cut down; which may serve as an attractive part about the "Community" if several homes were to be built on the subdivisions),  2 water wells, 2-inch water meter and all the utilities; how difficult would it be to find a developer to pick this up, have the deal assigned to, pay closing costs, and pay in cash?

You'll have most of your mortgage covered with rental income and, with an FHA loan, you can cut the amount of cash you need in half, possibly even more.

I’d rather go direct go the manufacturer and cut out the middle man- but US Modular talked a good game (sounded sales pitchy, so I’m not sure about them yet) and I also found another company out of Idaho with a local representative that I’m waiting to hear numbers from.

You will be the lucky one to cut the check for any back payments. 

You are already in over your head and it's better to cut losses than to let it sink you and your credit.
