Start out by living well beneath your means to help save

If they terminate outside, we don’t want it to be dripping water right at the foundation, at least put a rock or splashblock or something beneath it if you don’t want to extend the drain line farther away from the home.

Most of them were more interested in building their down line of agents beneath them than actively selling real estate. 

I'm scared to know what type of damage I will find on the floor beneath the tub.

I posted an A4 letter size note beneath the general mailbox and I posted an A4 letter size note on my window.

Similar to glue down vinyl plank, just without the glue ;) What's the flooring like beneath the carpet?

Window beneath had a one inch gap from improper installation.  

I just keep a whole bunch set aside that is more than enough to cover anything that could go wrong and i make sure to live beneath my means so reserves are never a problem.I would encourage the readers of this post to think bigger than "how much from a specific property do I need set aside" and start asking themselves "what is a healthy amount to keep in reserves to cover each property". where the money comes from doesn't matter, just that you have it.

If they slope down, the course of action that may be prudent would be to jack up your joist system (slowly) and then place some shims/etc under the existing beam where they are supporting the existing joists. 

It's not beneath me or anything - it's just I'm rolling on very aggressive rehab projects and I feel like my time should be more valuable than that stuff.Still would appreciate any other feedback you and others may have, though!!!
