I finally have an  excepted offer and should be closing by the end of the month.  

Get pre approved with a lender (either conventional lender or a hardmoney) so as soon as you find something, you can make an offer!

If it stays on the market for a while, the prices tend to drop and the seller may be willing to accept a low ball offer.

FYI -- In addition to the $495 Professional Edition that Michael mentioned, my company realdata.com offers a $159 Express Edition which is geared more toward multi-family property.

Otherwise I wouldnt offer one. 

A vacant, non-comparable unit owned in San Francisco must be offered to the tenant being evicted.An owner who wishes to evict a tenant for owner or relative occupancy must have at least a 25% interest in the building, if the ownership interest was recorded after February 21, 1991.

Maybe a good place to start for getting an idea (and understand that you could offer whatever you wanted on these properties), is Milwaukeemultifamily.com.

My buyers made an offer on a home that had $60,000 in a HERO assessment at 8.75%.

Based on those answers the insurance agent should be able to offer advice on the route to take. 

Instead of, or in conjunction with, other savings vehicles, consider just ONE rental property and all the benefits of the right property will offer over time: Cash Flow, Amortized Equity, Passive Activity Losses that "may" lower your W2 tax bill if you have less than $125k earnings, benefits of inflation in that not only are tenants paying down mortgage debt and rents increase over time, the debt itself becomes devalued, costing less in actual dollar terms.
