What I found was, yes it was nice have additional income, but each project seemed to always interfere.

That's nice, but magical thinking.

Appliances look nice until the pet hair destroys the fan on your nice stainless steel fridge and you are out another $1k+ to replace it... 

Nice to meet you.   

Top 3 reasons owners hire PMCs:1) No time to manage correctly2) No time to learn how to manage correcly: laws, documents, processes, etc.3) They're too nice and need someone to "save them from themselves"A good PMC can usually earn their fees by better managing the property/tenant than the owner, thereby:1) Increasing owners net profit2) Decreasing owner's time commitment, stress, headaches, etc.No matter what though, you should always plan to commit a couple of hours a month to manage your PMC.

I will take that over 200.00 a month positive cash flow :)  All the while running my Capital Partner business and funding over 120 deals a year for my hand picked clients. lThat's a nice combination.

Nice to see Zillow agreeing with every sales person from Buffalo LOL.Buffalo is a good market to invest long term if you get a good property, on a good street, in good condition.  

For me as well as the seller.First, you have to define Sub to financing.Do you mean the reckless kind where you overpay for a property, take over the financing and borrow from others to cover closing costs and holding costs when you have no money, no credit, no income, no reserves and can't tell a warranty deed from a deed of trust and you close on the kitchen counteror do you meanbuying below market value, already having a nice income, having reserves, using escrow and title, already understanding the due on sale clause, have done a lot of creative purchases and know when to use and when not to use creative finance and how to recover if something goes amiss?

My mom lives in a nice house that she has paid off.

Its always nice to hear positive things about local people.
