More units being built in a market with rising vacancies should lead to the vacancy rate rising even more drastically over the next 5 years.Look at migration data for your market. 

If one wants to wholesale you would do better going to work at a Car dealer FIRST to learn how to sell ... and how to close.Most people simply can't close.. can't ask for the order do not know that there is a definite skill and methodology to get folks to commit to do business with you.. this again is why real estate license is a great thing to have it then gets you in front of the sales guru's who teach sales technique... which is as we know critical to success.. when in fact wholesalers are just real estate sales folks doing it mainly illegally in the first place...

They pull data from Airbnb and VRBO.  

It is possible that I could wake up tomorrow in bizarro land and LA could turn into Detroit, we could hit an ice age and the great weather could go freezing, an Earthquake could put us underwater (literally), people in mass could decide that they prefer Omaha, all the tech companies, studios, and VCs could decide to move to Fargo, but I don't think so and I've got decades of data to back that up ... just in case my thesis is wrong, though, I always have multiple exit strategies to hedge against those kinds of risks and always watch and question assumptions.

(Public Records) banks pull that data now.The biggest issue is you want to avoid mortgage fraud and the legals that follow those parameters. 

Although the property has been 93 to 95% occupancy, used a 12% vacancy in year 1 numbers and underwriting.Based on market data and rent surveys, 2% rent growth was a reasonable assumption.OE should be 50 to 55%, however in my underwriting I used 61% in year 1 projections to allow cushion.Yes, landlord pays water and sewer.
