A little bit about my experience in Real Estate… I started a couple years ago doing some house flips in Detroit ( It was a 2 year plan) then decided to sell everything, moved to Washington DC which can’t afford anything in the DMV area but last year I purchased a very nice 3500 SQFT Duplex in Shaker Heights, suburb of Cleveland.

New construction is certainly a viable option but I am seeing people have great success with the renovation of existing properties.

I think they hold all loans in house so could potentially be more creative.
