Master Lease on Duplex, Triplex,and Quad

[George Frye]

I am moving to a new city in a few weeks and dont have time to go through the normal channels for a loan. However I have found several duplexes, Quads and Sixplex that I would love to purchase as an investment. Maybe I can even move in one of them and house hack till I can get a permanent house to live in. 

I would like some advice. Do you think offering a master lease option on either a duplex or higher will be an advantageous for me and possibly the seller? Also what are some points I should be aware of before I go this route?
