BP Fund predicts that home prices will rise 3.3% in 2017.I have noticed much more strength in single-family homes under 200K, where the higher end of the market has been slower. 

The quality of the investment can depend strongly on the strength and stability of the association. 

Strength of Demand?

Play to your strengths.

I was curious about the market in the UK with the dollar gaining some strength (comparatively to history) but I really have no idea about taxes and other rules about investing and financing abroad, or how Brexit will come into play. 

This is not a strength for either of us and it's holding us back.  

Depends on your goals, your strengths and weaknesses, your risk tolerance, 

Depends on the strength of the tenant, asset type (retail, industrial etc.) and LL preference, but generally I would say allowable with LL approval would be the standard. 

how can i evaluate the strength of my buyers offer besides the amount they want to pay...meaning can i ask to speak to their lender to see how tight their credit/DTI/bank statements are....last thing i would want is my buyer's loan falling thru two weeks before i close. 

Find the strengths in each other, and respect and appreciate what each one of you bring to the table.
