I would like some advice on what my lending options are for the co-op my family plans for buy. 

I am not the OP.  

OP is an investor / wholesaler..

It is easy for you to be charitable with the op's money telling her to give more time however I'd say 5 months is plenty for anyone to make a plan, they just chose not to which his not the op's problem. 

Free leads that are motivated without lifting a finger (after it is set up).OK so that takes care of that.Now OP, this is what you do.

Showing activities increased since op, they shortlisted and vetted 3 potentials and signed best qualified (at asking $) for May 1st move in. 

@Omar WilliamsTo your OP, the quickest option/strategy is to find a partner.

I think the OP got good feed back many think you should not contract if you can't close or the only hope of closing is finding another buyer..  

., it sounds like you have multiple properties based on your OP.

@Jay Hinrichs I’d love to hear your thoughts a little deeper on this topic-avg 7-10 yr hold of an investment property.I agree with comments to OP on taking 10 yr ARM-can refinance when rates are favorable.I’m 5 years in to REI and not really looking to sell anytime soon-is the cliff notes version that ROE becomes so lousy compared to a 1031 that the astute investor just sells and trades up?
