The rehab took a bit longer than I would prefer but I did not have any HML to worry about.So this particular BRRR deal seems to have worked out and I have the cash back to do it again...and again..

I replenish the emergency fund and hope there won't be another call any time soon.If the repair is over $200, I can have several estimates from the PM's contractor pool and decide what estimate I prefer.

I prefer certified funds.

It has always been a plan of mine to try to purchase this 4-plex as well and since I am not getting the tenant interest that I would prefer, I think I would like to approach the owner sooner than later.  

I'm really looking for a mentor, preferably someone not to far from me that can show me hands on.

Personal preferences, etc.?

I personally prefer to rehab my properties before I rent, that way I collect more rent and I am able to refinance for more.

Your own appetite for risk will vary.Would I prefer a 20 or 30 year fixed loan?
