What I cannot endorse is the misleading presentations by some cost segregation companies to sell their services. 

The LLC will have to sell and buy as much real estate as it sold. 

New Builds especially but I know many who have struggled to sell in East Austin recently.

In my opinion, it can be a sign of builder/investor confidence in a given area if they're willing to put up the capital to build new homes in a given area: they believe there will be enough demand to sell their new products.

It’s taking Seller a while to provide the HVAC report but while time passes after due diligence - Flooring cost is way too expensive at the price point they’re asking for 130K + Care of property never took place till decided to sell so I’m not comfortable any longer - Home sits on corner lot on a slight hill with crawl space - Lots of weather changes has caused the home to settle + improper supports needed. 

If I sell you on this sub-to program, I get $1, so it's the best.

If so conventional will be better because FHA/Conv guidelines are the wheel house typically of mortgage broker and some times banker (synonymous names but they all do and sell the same product).Credit unions can sometimes do Fannie Freddie/conventional FHA too but generally aren’t that great at them.

We ran my in-laws mountain/lake STR for 7 years before they decide to sell the property. 

Take note of address, find the owner and see if they would be willing to sell.

If he is living paycheck to paycheck, he's probably better off paying off the mortgage (actually, he should sell the house and buy something more affordable and invest the difference).
