you can buy compression fittings at lowe's or home deport for this purpose.http://www.lowes.com/Pipe-Fittings/PEX-Pipe-Fittin...you can use them with all different pipe and tubing types, as long as the diameters match up.My recommendation could be to use PEX, it's more resilient, and easier to install (bendy, hooray).  

Imagine how many seeds you can plant if you put a 30 year mortgage on those properties, leaving 30% equity in each, taking that cash, and putting down 20-25% on a handful of other properties (or small multi-families) and what those “seeds” would grow to be in a few short years...Leaving homes paid off, in my opinion, are for those who don’t have much life left to live...

Upgrade light fixtures, get a nice mirror and distract the eye with some bold staging items (towels, rug, maybe a faux plant). 

They are investing in a business that happens to have a physical plant (the property being rented).

New Samsung plant announced this week also.So maybe after several years of 2-3% appreciation things are starting to change.

I guess we just wanted to get our roots planted with a house hack but we have to make sure the numbers make sense first. 

@Vincent Plant It is weird but at least you can calculate the financial impact.

Flipping a quarter to see who wins is not a good business model.My vote if you have no documentation is rip out the carpet, use some oil-based Kilz on the floor, and go over it with resilient flooring like luxury vinyl plank that is much easier to clean and repair when pets piddle. 

Funny thing, we wanted to participate with the rehab & decided to work on the yard, so we planted seeds & grass barely grew, so we decided to hire landscaper to do the grass!

as you probably know houston has large oil and gas industry- specifically in my area there are many petrochem plants and such (ei: pipe yards, fabrication shops, drilling compnaies)
