Let me know if you want me to take a look.As a side note, check out Cozy.co for rent collection and also a way to market your property and receive standardized applications.  

Collect cash flow and eventually cash out refi and pull out tax free cash for your next purchase.I wish you the best.

Make an offer with all necessary contingencies to bail if the repairs are more extensive that you expect.

Can you please give me contact info for a great Collection Agency.

I'd say ASAP as you don't want that contract to go stale, over a year, best to extend it as you have and keep up collection attempts.

We go through all the most important numbers (collections, net leases, renewals and service requests).

That $750-800 is only possibly rent collected,  In actuality you will be paying thousands in legal fees/turnover/damage to collect some of that rent.2. 

There are a variety of different ways to do this; whether that be pursuing properties in need of extensive renovation and likely requiring cash to close, targeting properties with certain zoning that allows you to split the lot/add additional structures,  etc. 

Time in management, repairs, damages, collections, evictions, police calls, complaints......IMO you're not really ahead as you are earning every dime you can collect!

Needs new AC and extensive work although I don't know how extensive yet.
