You can Join your local REIA, Network, Joint Venture with others, If you know family & friends willing to use some of their IRA/401K.You've mentioned "reading" peoples post have you listened to the Podcasts here..they cover everything about REI and they last about 1 hour give or take a few minutes.For your personal life I would urge you to pursue improving your credit.

No central air though and floors look like it could use some renovation.

Once you are more comfortable flipping and have a good team in place (i.e. contractors, realtors, lawyers, etc.) and your speed and predictability improves, then I would start using leverage to scale up your business.

I used this guy 8 years ago and he was 1/2 the price of ASi:  www.cariniair.com/ Carini Heating and Air Conditioning is a San Diego HVAC offering heater and air conditioner repair, replacement & installation.

Do you plan on making significant improvements to the structure/units?  

. , I had a similar issue on a 100 years old house too.in my case i resolved by improving a badly designed/implemented gutter system (all the rain water was just dumping over the walls, soaking into them then getting into the basement) and diverting that water away from the house. 2xprimer + 2x good paint.maybe this is the case here.if you don't want the hassle of getting rid of the existing tenants, vacancy and finding other (hopefully) better suited tenants, maybe first you can just paint the place inside and outside and resolve any safety issues (rails). what did you repair to the place?

Michael McDermott I just contacted Lee Stivale what a breathe of fresh air. 

A letter can be sent if it helps.My profile has a few of my credentials I believe, if it is not enough, an improvement is needed.

@Kimberley ThompsonMany of the BP tools, though improving, are quite U.S.A.

The property needed some improvements, but nothing so serious.
