E.g. you can structure two separate transactions where you close on a purchase and then separately borrow cash from your recent seller....the problem here is the intent.

The tougher part will be finding clients that want to work with a part-timer that has no experience and little time.If I were you, I would focus on dentistry where you can make really good money, then use that money to invest in real estate on the side.

I'd look for real deals, where you can elicit some owner financing to help offset the downpayment.

Additionally borrowers could be asked to go once step further and provide copies of 12-24 month bank statements reflecting where the payments were withdrawn from.

are there any sites where I can directly search a list of qualified tenants?

Where do I sign up?  

I guess that's the area where you come from and your mindset. 

Where is the original $70,000 coming from?

You need to find out where your risk profile sits on the spectrum.   

Or determine where and how you want to get involved, raise some capital by selling or using your current properties as assets and get involved that way with or without partners depending on your budget and goals.
