We currently owns 60 condominium units in Houston Texas and several multi family properties in the California area.

GDP, household income, unemployment rates etc?

And owner occupants, for rent to own, who did NOT pass prequalification that you can qualify in the next 12-36 months, have a strong combined household income, and are looking to purchase in the $150k+ range. 

As a single mother, it's difficult to foresee a stable financial future when only earning one paycheck in the household.

Are they definitely "condominiums" in the legal sense(which means there is only one parcel number) or are they I fact two "townhouses/zero lot lime homes" (having two parcel numbers)?  

what is requirements of building a condominium complex and what's the cost of it?
