From a property appreciation / ROI-on-sale point of view, its unclear how attractive such a property would be for a future buyer.Would really appreciate your thoughts on this Invest 5S proposition or similar build-to-rent units.

For example Avondale typically has 2-4 units for sale with 2/1s at $1200-1600.

I'm looking to whole sale now in the Los Lunas area 

I got skiddish and did not close.. same houses a year later are going to sale at the courthouse steps for 30 to 60k..

There are cool new chargers that plug in right behind the power meter.

I am a big believer in working with what the market offers you, instead of trying to grow oranges in the winter.Back in 2010 that was foreclosures, in 2015 it was short sales. 

@Anthony Dupre depends on the lender. one possible way to avoid due on sale is to time it with Refi.

Remember, this is still a sales type of business so be very careful on who you choose to work with.

Don't forget the people on the demonstration are just sales people.  

This will give you a base for what you need to put in to get the best value out of your properties when you are checking ARV and getting the sales price you want along with selling quickly.
