If I’m being honest (and I may be over-thinking it), I’m worried about getting a job for a wholesaling company, and the possibility of burning important bridges in the industry when I do leave to start wholesaling on my own.

Honestly if you've had it for more than 5 years and you're having to pay $450/month (not including repairs and other things), I'd look at selling it. 

To be honest, I wouldn't base my investment decisions on appreciation only.

No idea about SF to be honest.

@Junix Alcayaga @Andy GreenOne thing that really helped me starting out, and something I need to get back to doing honestly, is reaching out to owners through cold calling and mailers.

By doing that, you keep your numbers honest and still account for some hidden expenses, there’s a good chance you won’t be over spending.

Every time you spend a lot of time interacting with an investor you’re raising money from him or her for your next deal.You have to be open and honest with each investor, every time you meet - even when things don’t go as planned.

Honestly, I didn't fully understand the numbers like I should have going into this deal.

Honestly I think you'll learn more and have more piece of mind at least starting out here.

Honestly, without an oven thermometer, I'm not even sure how he noticed except it is his business and he was looking for a repair opportunity.Based on advice given above, I will make this the last non-urgent service call and let him know that if he isn't satisfied he is welcome to exit the lease.
