I usually run several CMAs, with different criterial, and of course compare tax appraisal value with a wholesale price, add 5% as a fee to a transaction, in some cases.

That is if purchasing EXISTING performing investment real estate AND have very good clarity of every facet of the transaction ESPECIALLY reasoning for seller selling, AND you have decent market intelligence. 

I've had business and conducted hundreds of sales transactions and find it very underhanded.

With record low inventory and sales transactions there's no low hanging fruit.In this market we think the best opportunities are value-add (BRRRR'ish), zoning changes allowing density (ADUs), or seller financing deals (buy a lower rate).

It might take me 15 seconds more per transaction to do it this way, but it’s what has worked for me.

I've been apart of transactions where the deal was structured by offering the seller a percentage of the difference between the original purchase price and the new value at refi.

Alternatively, you may want to consider switching to a platform that offers this level of transparency.Additionally, on both Airbnb and Vrbo, if you have access to the account, you can view the transaction history.

• Off-Market Sales: Were any off-market transactions missed?

Equity in C/D located real estate is often merely paper equity...equity represented in an appraisal report that is less likely to materialize in an arms length transaction. 

Transaction volume is basically non-existent.
