Future workers need to adapt in order to have same or better quality of life than us so I'd like to have at least 100 rentals by year 5.  

In general, the adjusted tax basis of a primary residence is the purchase price of the home plus amounts spent for capital improvements that have added value to the property, prolonged its life, or adapted it for a new use.

This is an excellent tale of adaptability, perseverance, creativity.

Maybe later, when I'll learn how to do it, I can adapt it in Spain, but later. 

Inspiring story of adapting and overcoming. 

If one looked to me they'd find many MANY evolutions, adaptations, shift's of strategy actions. 

Change and adapt as needed.That's IT!  

Once done, I can back out the copper male adapter if it's not badly corroded and fused.Yes one of my fears is the connections are badly corroded which will mean replacing the fittings, and if i have a hubbed fittings with the bathroom double tapped tee on top with a street end into it, I have to mess with that it may turn ugly.Even worse if the pipe below that fitting has a vertical crack into the concrete slab.Or I can even tease out the copper pipe after having the two openings because it's strapped to the framing in between, or the holes are drilled so close a copper coupling cannot pass through.I may have to replace with same copper since PVC may be too large OD to fit through existing stud holes.

There are a couple issues as I know things vary state to state.What issues vary by state so that I may adapt mine accordingly?

You might ask your tenant if he would have the Ocupation Therapist or his Case worker to call you with the kinds of adaptations you would need to do, and if there is a way the state or medicare can pay for them since he does not own the home.
