@Douglas Snook My thinking on the 93A approach is that the tenant will likely be awarded triple damages.  

So, instead of threatening, I would approach the seller with additional non refundable earnest money if you fail to close again by 9/15.

Is this a good approach?

I think that approach will be more effective than trying to come up with one on your own.The scripts you can find from professionals online are scripts that have been tested and tweaked after hundreds & thousands of calls.Use search engines and reach out to active wholesalers to find the right one for you!

I'm curious to hear what approach other investors think is most favorable.

In addition, I listen to Bloomberg podcasts - especially the Business of Sports. 

I would take a more extreme approach...

@Pat Jackson, with the paneling I might take an incremental approach.

Now we are looking to take a more business focused approach and we are actively engaged in looking for cash-flow properties from long-term rentals in Granada.

I was recently approached by an investor who wants to sell their quadplex in the SW side of Cedar Rapids IA.
