Here are a couple of suggestions to speed things up:1. 

I used there platform/CRM to get the place under contract but went about it my own way to find the buyer, therefore the speed of the closing was not representative of the companies ability. 

This is your adjusted cost basis. 

This is how I analyze risks and make risk-adjusted return decisions:Identify the Risk: Vacant units could be a sign of high vacancy rates. 

WE EXPECT to come in and fix sheetrock settling cracks Grout.. doors that may need a tiny adjustment etc etc..

I would take your evidence to them and demand an explanation and possibly an adjustment. 

My guess is that your adjusted tax basis is fairly low, and that you're looking at a whale of a tax hit if you don't do a 1031 exchange. 

There are some new hits that were recently announced from Fannie Mae for the LLPAs (loan level price adjustments) that will increase the cost/rates for second home financing.

With property tax adjustments and the mortgage company requesting an additional amount for possible future increases.

Basically doing larger numbers in one type of marketing gets you data faster that you can use to adjust based on your results.
