She has an attorney on the job who has served him with a notice I’m not sure of the days just yet.

I would proceed to eviction for non-payment serving all the required notices. 

Is there room to raise rent or decrease some expenses?

I've been doing research into how to do it and as far as I can tell the process is that I pay off their missed payments and then do creative financing like subject to or owner financing with the owner to get the property.My question is, can I still buy a Pre-Foreclosure by helping the owner to pay off the missed payments and then get the property subject to if there has already been a Notice Of Trustee's Sale?

The downside here is that this will require two loans, which will decrease my ability to purchase additional homes down the road with traditional financing.

Notice I didn't mention spending that cash?

After I received my SS4 form I noticed my Social Security was on both of them.

No eviction, she's moving voluntarily supposedly...I say supposedly because she hasn't given me proper notice.

  - Susan has not given notice that she has moved out- Her adult son is still at the property - he is unstable and verbally abusive- The police won't do anything because Susan will not file an abuse complaint against her son Roy- Susan has not maintained the house appropriately meaning there are holes in doors, broken cabinets, damaged floors.

I then sent her a notice of an owner inspection to see said improvements.
