This five-year expectation has become the industry norm.

there has been a lot of talk in the industry about building multi generational housing..

All this is why, I believe, it's a rare thing in the REI industry. 

@Richard Anderson: You've piqued my interest.Do you happen to know if there are guidelines in the banking industry as to how to handle the Due on Sale Clause when a seller sells on Executory contract to another individual?

Also where there are changes in regulations that may require lenders to change servicing agreements which affect who services your loan.I know that's a pain but as things change -- unfortunately, investors will be impacted by changes in the lending industry - and that includes LOAN SERVICING CHANGES.It’s a total cluster between the banks, their loan servicers and their loan servicer’s sub-servicers.

This is why i love BP where else can you go and find so much wisdom and insight among professionals in our industry that are willing to share their experiences.

I would love to eventually look more into hotels and perhaps the restaurant industry.

.)- Average days on market- Absorption rate- Historical data on rents and sale prices in the area- Population growth- Main economic drivers (industries, individual companies, etc.)- Crime stats... if you know specific zip codes/submarkets that you'd like to target, the best data will come from local precincts. - and more..I'd recommend remaining active not only here on BiggerPockets, but in other valuable RE investment networks that you can find - i.e. local meetups (meetup.com, eventbrite, BP local events).
