Recommendations?

I recommend getting a good CPA that is experienced in the real estate niche to help you put some of these puzzle pieces together. 

I would recommend writing a new lease.

I highly recommend staying well-informed about tenant/owner laws.

I am looking to connect with seasoned investors who can offer advice and possibly recommend trustworthy contractors and inspectors.

Looking for recommendations of best electronic locks (coded entry) that also have key access.

You always have the option of walking away.My recommended course of action is that you extend the contract so that you get YOUR OWN hvac guy can get out to take a look.Your hvac guy won't mind the quick and easy job of diagnosis, give him an hour or two of work, have him write up a lightly padded repair estimate and hand that over to the seller and ask for that amount to be credited.

If you have any recommended lenders, it’d be greatly appreciated!

However, I would definitely recommend spending some time beforehand learning as much as you can about your market and learning about rehab - as mentioned in other posts, J.
