Your best bet is to contact a 1031 Intermediary to ask these questions as they are the professionals that will be involved in shepherding the exchange.

I bet there are some Stay at home moms that don't even know that.

Most duplexes are located in poor areas of Houston.

Your best bet for mold is to get a mold remediation company out to deal with it.

Fast forward 20 years from first reading Rich Dad Poor Dad, I've built up a portfolio of 50 rental houses, a 10-plex, a couple office buildings, and a tax-free annual net profit of around $200k.  

My portfolio consists of multipleasset classes and multiplemarkets so unlike others we are prepared for a poor economic cycle as much as growth.

I read the book "Rich Dad, Poor Dad" by Robert Kiyoski and it lit a fire in me.

Possibly adding more value and then doing a refinance will be your best bet and highest ROI.

@Thomas Waski Family members who live out of the area and not interested in spiffing up the place, reveal themselves with poor photos and uninformative descriptions.

I have experience with cellular concrete in a commercial application as mass-backfill (15,000 cubic yards) for a newly constructed building where existing soil bearing pressures were poor.
