@Samir Shahani it is a debt relationship with a promissory note and a deed of trust on the property in second position, not an equity relationship.With doing the model this way, it minimizes my expenses such as cap ex, maintenance and repairs, turn over and vacancy, while I am able to capitalize on above market rent, the option fee, and the sales price bring about 7-10% above current market value without needing to pay realtor fees or concessions at closing.

How you minimize disputes?

Once your first property is tight with good tenants, less deferred maintenance, and fewer possible capital improvements needed after addressing major needs, month to month activity is typically minimal.

I've been approached with an off market opportunity that is valued at $1.4 million. The back story is that a son of a deceased investor can't manage the properties, so he is looking to liquidate.My realtor approached...

I would have thought the marketing would take place before the tenants moved out to minimize the time the house is vacant.Are there standard items that are typically done (besides a deep cleaning of the property) during a turnover? 

After refinancing, you get a free property and cash flow minimally.

Much of the information on this site is about how to obtain rental property while minimizing the amount of your own personal cash you invest in it, however they key word there is "minimize".

Is there a good way to approach this process to minimize blow back?

So I can afford very very minimal down payments. 

They’re TAW and have been for years, so upgrades have been minor and minimal during that time.
