If your hard money is costing you 15-20% and your relative is willing to lend at 10% there is no need to offer more. 

rdeLocaleAttr=enI'm expecting an inheritance in the next couple of years (in probate - I swear, if you want to get revenge on your relatives, leave a bunch of money and no will) and am researching buying cheap homes for cash and selling them with owner-financing. 

I expect to come into some inheritance money in the next couple of years (it's in probate hell right now - if you want to get revenge on your relatives, leave a bunch of money and no will, and 7 heirs to fight over it).My background is in property management, and initially, I was thinking about buying a cheap rental, paying cash. 

@Jing Tagle  Well, let's just look at what they got from your relative just last year

Technically, your relation to him may disqualify you, so do some research and call local title companies just to be sure.Good luck!

Is the main reason you are interested in this property because it will help your relative with their tax situation?

Your relative should have the instinct to know if he is playing his game. 

I have been actively listening to BP podcasts and reading and there are a few options but i am still unclear.It is much more evident what to do if you are into BRRRR, because then you have an option to seek the short term private loan or even borrow against the credit card or your relatives.

Not that you would be a jerk landlord, but even if you're pleasant, you are better off keeping your relative position of power as their landlord.Then, just send them notification that the property has been sold to you and where they are now to send their rent.  

So, if you have the receipts paid for by your relative, and proof you sent the relative money to reimburse them, you have an acceptable paper trail, in my opinion.
