I received estimates from residential window manufactures ranging from $40 to $76k for 25 windows.

Latitude Property Management (http://chooselatitude.com/) has excellent reviews and is run by @Neal Collins who is active here on BP. 

We received our counter offer, and we're in the ballpark, but now REALLY wish we had an experienced investor to check our assumptions. 

(and wasn't there less than 5 mins prior, so think she was stealing it) I put it back, give her the check and receipts and ask her to sign saying she received the check and understands the charges for cleaning, carpet damage.  

A few weeks ago I received several job offers after applying to be an assistant property manager, both from companies that managed SFRs and small multi-family, and those managing large apartment complexes.

I'll definitely let her know about all the advice received.

It’s too bad your renters didn’t tell you when they received a certified letter saying the Hoa was trying to get ahold of you about a violation which I assume they would have as all fine notices I’ve received have come certified mail.

One page for distressed homeowners to submit their property, and possibly receive instant cash offers.

This concerns me because of the reports I have received from the neighbors that picked up these things up from the new residents.

Always ask for a receipt to confirm the transfer has been received.
