As far as it tearing up the front end of the car, that seems unlikely if they are driving over it at a slow speed.Bottom line, that drive way was in that condition when they rented the property.

The rule is that you must have acquired (constructed) unit B with the intent of holding for productive use. 

Fannie Mae generally requires lenders to obtain a two-year history of the borrower’s prior earnings as a means of demonstrating the likelihood that the income will continue to be received.However, a person who has a shorter history of self-employment — 12 to 24 months — may be considered, as long as the borrower’s most recent signed federal income tax returns reflect the receipt of such income as the same (or greater) level in a field that provides the same products or services as the current business or in an occupation in which he or she had similar responsibilities to those undertaken in connection with the current business.

The FNMA product used to be a no-brainer because of the rates, but now you can get a 30-yr fixed rate, 30-yr amortization in an LLC.

This is a separate loan product from conventional (Fannie Mae and Freddie Mac loans). 

A liquid additive like the following might be just the ticket:https://www.homedepot.com/p/Custom-Building-Products-StainBlocker-32-oz-Stain-Resisting-Admixture-Additive-for-Grout-SBG32/202525433 If you're looking for an off-white grout, I would feel confident recommending either Antique White or Bone with the above liquid additive.

The 'new' debt service coverage ratio (DSCR) driven products are more attractive, though, IMHO. 30-yr fixed rate, 30-yr term, rates in the 4s (right there / better than banks) and no debt to income ratio BS.

Sound barrier performance is based on density of the product. 

There aren’t many cases where you can choose which product to use and have them both make sense.

These local prices are running up quickly, so "deals" are a lot harder to find.If you're having a good experience so far with this house, you might want to look into the FHA 203k loan product for your next project (if you haven't already).
