Just make sure you get short-term renters insurance and you'll be in a good spot.

Can anyone fill me in on which area/cities are the up and coming spots that are worth investing in? 

I want to share, maybe not success, but my experience starting out in real estate investing.I do not have a blog so felt this was an appropriate spot.

@Steven Steffel is spot on.

The paint & primer is all I use when painting but by itself it is not effective enough to cover all the mud spots without being seen.

if they're not the deal could be sold already. . so you better check that before you move forward. then drive there, estimate the rehab or call your contractor to give you an estimate on the spot. don't wait 2-3 days.. the deal might be sold. if the deal is good chances are lots of people are going to check it and send offers. .so you want to be the first in line direct to seller or direct representive.don't take anyone word. the real estate investing world is about making money. . and in most cases making money fast.. so trust only your own judgment.  

Tried to pry tiles off in random spots and they stuck well.

If it is then what Chris wrote is spot on, this contractor is not qualified to do the work. 

Kevin is spot on.

Assuming it's not an A+ luxury unit in the most desirable part of town, then I'd usually recommend a plastic shower curtain instead of a glass door, because it costs much less and can be changed easily between tenants (whereas a glass door often accumulates water spots that can be difficult to fully clean after a few tenants...and, as you mentioned, if a tenant breaks a glass door, that could be a costly headache).Also, assuming it's not an A+ luxury unit, I'd usually recommend going with a fiberglass unit (either tub or shower) instead of tile, because tile is usually more expensive, and it can be more likely to begin leaking, and it requires more upkeep.
