Though you should learn some basics so you're also not wasting money clearing a drain. 

It would be closer to existing water lines and drains for example.

- remove existing tile - remove drywall in surround and window area to the ceiling - replace drywall with hardibacker redgard hardibacker large porcelain tiles (16x16, 12x24) with smallest grout spacing possible- highest quality caulk that is mildew-resistant - tile floors, 4" base/behind/beside toilet, in addition to tub surround all the way to ceiling - angle tiles away from block window - re-install shower curtain rod  - replace fan/light with higher-performance model with humidity sensor - inspect fan ventiliation to confirm vent going through ceiling - inspect bath, sink, toilet plumbing and waste drainpipes - add quarter turn water shut-off valve - replace bath fixtures to single stem handle - replace bath drain with grid drain

I am currently throwing money down the drain by paying $850 in rent at the moment, and noticed that I can be paying for a mortgage for almost the same price.

Over time with rent growth eventually the investor might get to 200 a door but with everything new there are little capital expenses that could be a drain on profit.

well, the only time the septic and drain field needs to be replaced is when the filed doesn't take any more water at all.

Extending the drain some...

The ones who, when you leave their presence you just feel drained.

We were not planning on doing as much as we did, but we wound up gutting it down to the studs and replaced all electrical, plumbing (including the main drain), etc.  

Kitchen Cabinets with fist sized holes, an overflowing AC drain that went unreported for lord knows how long, causing standing water & mold growth along the entire back half of the house (hence the water issue), and we found a nice pit bull puppy (no pet policy) that conveniently ate carpet + pad, chewed window casings and doors in EVERY room.
