Bought one some a few years ago and sold it later for profit without doing a thing. 

I've only bought out-of-state properties (living in Los Angeles) and it's certainly been worth it.

I used to work with Yadkin Bank but bought out by First National of P.A. and they have been a NIGHTMARE even with existing loans.

He started renovating it, but did not finish, and bought a house and is moving out in a few weeks.

We bought our first property because of the long term tenants that were in there.

When I bought my current house, I was looking at Millbrae as a stretch, but settled on south city because it was realistic.

I put 8 smoke alarms in my single-family rental - Lowe's sold a 6-pack of the model I used, and then I bought two more of the same model individually.Also note that if wired detectors are required, they may not all have to be exactly the same model, but they do probably all need to be from the same manufacturer. 

years ago my dad bought a house for $15k.  

I bought this building despite their move.

I was dead set on getting one of these, but to my misfortune, an investor bought BOTH for cash.
