That's a terrible idea.He should either install a smart thermostat that allows him to set limits, or he should remove her from the property.

Hey @Eric Andersen, so there are a lot of regs in the DFW area.https://www.fortworthtexas.gov/short-term-rentalsRentals are not allowed in residential districts: A-#, AR, B, R1, R2, CR, C, D, UR.Dallas recently banned STRs in single family homes but there was an injunction that blocked it.

Her mother is willing to (co-sign) and has excellent credit and debt to income ratio that will more than allow but I’m not sure the best way to structure this for the house to still be in our name?  

Operating in the Luxury SpaceWe focus on properties in the $1.4 million to $1.9 million purchase price range, which allows us to sell finished projects in the $2.5 million to $3 million range.

Would cash-flow very little.Obviously, a combination of the above is possible (pre-sell all but a few units, nullifying the profits, and therefore taxation).My feeling is that the first option would allow me to use profits to build something bigger (e.g., acquire another plot). 

(Few lenders will allow no US credit, but will result in an LTV reduction. 2.

Not a lot of municipalities allow that sort of structure as living space in our area.

This has also allowed us to provide some excellent incentives for our investors, locking in long term debt currently at 3.75%  through our in house financing program.

They have the lowest rates we can find and since they are 30 year fixed...they allow us to cash flow better...which helps us qualify for other loans later.

With our unique model we allow those to scale quite quickly.
