I'm currently investing in buy and hold using the BRRRR method.

Problem is it's the same brick but colors are probably mismatched due to fading from being in the sun (this is in Las Vegas).But the concern is this-- the retaining walls are really part of the community fixtures that happens to be on the homeowner's property.

I have a bi-yearly contract with them to maintain the units and they currently have a new policy where they check for mold in the duct work by an intrusive method and they are finding slight mold growth and are recommending this device called Nasa Air Scrubber (~$1200 per unit). 

Please feel free to chime in with any suggestions or concerns with my analysis.

And I make sure I keep all conversations via email and text to confirm and have proof that I explained my intentions from the beginning BEFORE I sign anything As a Texas lawyer, this is what concerns me.

Please feel free to chime in with any suggestions or concerns with my analysis.

My only concern is a power outage during a rain event - in which case the sump pump in the basement would overflow and flood the basement. 

I'm not necessarily concerned with the cheapest, as much as I'm concerned with the most effective.I appreciate everyone's help!

@Kris Wong That exactly is my concern, will I be able to find multiple properties in Austin totaling to 2M in 3 months, to complete a 1031 exchange.

School ratings do affect families but there are many good schools and if it is a concern for a buyer they tend to research the zoning and buy where the rating are the highest.
