I was required to add exit signs in the shared hallways / stairs, and to add interconnected heat detectors in all units, and to upgrade all smokes in all units to be hardwired, and to create 1-hour fire separations between the three units, which we accomplished by painting the ceilings and walls shared with stairwells/common halls with intumescent paint.

It's not made for today's load either amperage or heat related.

I get that request daily  ;-)  U should get on Pace Morby's free facebook and put that out to their crazy tribe.. something may come of it when you have thousands in the tribe and its his home area.. thats what I would do.His community is focused on neighborhoods where you need to pack heat to survive the night.

I like that you are pushing to get it done though as the spring market is really starting to heat up. 

New heat sensor smoke detector because the old one went off any time the stove was used.

If you're concerned about how the yard looks, I would recommend using grass seed that is native to Texas and can handle the heat in addition to xeriscaping to save on water. 

Purchase price: $220,000 I bought this 3 bed 2 bath condo and renovated from top to bottom: new floors, painted everything, granite in the bathrooms and kitchen, changed all (light) fixtures, and replaced the heating and air system.

It also has a burner and a heat exchanger.

Would anyone be able to give rough estimates of electric/heat/air bill.

Reason I tell you to only use part of the $50K is because its better to use the banks money.That also allows you to stay cash fluid and have reserves for repairs and renovations.
