I really would like an app or site that allows you to compile a list of properties with notes on the spot, and bonus points if it pulls up any info on the property as well. 

This is not yoursituation, but just to walk through the different thought processesin Holding/Selling that a friend of mine is going through.Helped my friend getinto the Self Storage business and walked him through the wholeprocess from evaluating the market, selecting a site, developing thesite, systems, financing, insurance, etc.

Managing 17 shopping centers and selecting sites for new developments is no small feat—kudos to you!

dogsbite.org is a propagandist site created by a web designer who was bitten by a dog.

One of the sites I like to check (https://apartmentloanstore.com/seattle/washington/cap-loan-r...) peg this between 5.15% and 5.70% (assuming it's in the suburbs).

@Drew Sygit @Gregory Schwartz From this HUD map it is 17 States/DC, and another site says 22 States which may reflect some more recent updates.

It isn't impossible but as @Jimmy Lieu mentioned, there is a steep learning curve.Depending on your liquidity, out-of-state buy & hold rentals could be your best bet if NYC investing is out of the picture.

I’m not a betting man.

If you are just downloading data room info from brokerage sites and plugging into a model, you are refining your skills on the "act", which is certainly necessary and helps make the process faster.  

But, I bet-ya it's also effective.
