Financing question private lender to homeowners mortgage

[Kyle Plants]

I’m sure I’m not the first to think of this idea but I haven’t heard of anyone discuss it. My plan together started in my buy n hold venture Is to gey a prIvate loan from a famIly member for tge coast of the house plus rehab to get It Into rental condItion then turn around and get a 30 yr fIxed rate Mortgage and use that money to go buy more properies, rinse repeat. Ive asked a couple of my babI buddies but none of them have replied to me If thIs can be done. Anyone on BP ever tried thIs before or know of any reason why It cabt be done? Seams lIke the pwrfect In strategy.
