Also, I'm not sure you even put much weight on familial status and gender, other than the relationship to financial inability.I think they are just trying to give you a "heads up" about potential hazards of a HUD lawsuit and the best way to avoid one.

If the front foundation wall (that has load against it) has to be over 10' tall, then Sevier County will require an engineer's stamp on the drawings.

I'm familiar with IRR, and I could see it having a place as an output in my analysis.My main goal is to capture the most commonly used metrics -- and based on the people I've talked to, books I've read, podcasts I've listened to, and blogs I've read, the most commonly used ones seem to be cash flow, CoC Return, and Cap Rate -- and allow a person to compare many properties using all of these metrics simultaneously without any a priori assumptions about which ones carry more weight than others.

At this rate it will take 4 days just to load one property.

This is no load, low expense ratio fund, and if you are concerned about the market just spread your investment over few months, use dollar cost averaging strategy.

If you are dealing with an addition built on 12" beams (or if the original foundation is old and not built to current standards), the repair company might not be able to push the piers down to refusal depth or psi due to the beam not taking the load, thus leveling it, but not guaranteeing it will not continue to move in the future, thus not providing warranty.9.
