Look outside the traditional lenders.  

My student rental turnover is considerably higher compared to traditional rentals and not uncommon for the majority of units to only have tenants for 1 year.  

generally, motivated sellers cant wait 30 to 45 days for traditional financing. 

There is no reason to not have traditional AND unconventional ways of acquiring property.  

I would say I would like to take a conservative approach to finance with either a cash purchase of a low end property or a traditional mortgage and use any free cash flow from a property to ether pay down additional prinical or save for the down payment for future property.

Most people on this site are really good and have a lot of experience so I'm sure you'll get some good feedback.In regards to the LLC just remember that when you put a home under one on title it will disqualify you from getting traditional financing.

@Christian Hutchinson  Find out if the doctor parents can pay 75k cash, because it sounds like that is the only conventional way you will be able to sell it to them because they will not most likely qualify for financing. 

If you are using traditional financing you will likely need to keep buying in your personal name.

I have seen banks wanting you to own the property for 2 years before they will give you a loan on it.If you have not owned it long enough to satisfy a bank, you might be able to approach private lenders in your area.Best thing is ask everyone (banks and non-traditional lenders) what they will do for you and see what they say.

Sky Mikesell here based in Charlotte NC. if this is a foreclosure sale then most states allow for an accelerated removal process of any stay over occupants. .. when i say accelerated that means it is faster then traditional eviction proceedings.
