It is never rude, it is business.I would question your motivation of going after a property that appears to be priced at or above retail value.

I appreciate any and all advice and feedback.I am interested in leasing a 50yr old stand alone retail/office building for a business I will be opening.

Now, his funding would be ideal for flips (either flips to retail buyers or flips to turnkey investors).

Most people can get retail pricing.

I offered her to leave my name and number along with a brief description about how I could purchase the property from him for cash at whatever time is convenient for him/them.I got to thinking about possible owner finance options while my main goal for this property is to rehab and sell retail.

I'm in Seattle here and over bidding on a retail listing is very common.

I find it hard to believe that a $50K cosmetic rehab is keeping all the retail buyers away.

You'll find that many of your buyers are rehab'ers, and many rehab'ers don't like anything less than 2 BA - harder to retail quickly.Otherwise, you're right on the money!

My brokerage does not want to be associated with anything except the higher end retail market and sales. 

If you go to sell a home at retail you'll need a good one and they'll charge between 5%-6%.
