I told him to be more active here on BP, as I see somebody here just about daily looking for MF deals in this area.

Although, until you close on a deal, it's more like "daily grind".

Zillow estimates are a joke, I always rent above what they establish and the thing fluctuates on an almost daily basis.

Trulia & Zillow are usually pretty reliable and offer immediate or daily email updates and at least Trulia (maybe Zillow too) can also do notifications so you get immediate info on your phone instead of having to keep checking your email.But in a market where things are going UC in 2 hours I’m not sure any of the online services are going to be real-time enough...

Second, while I have the numbers for how much each apartment would cost to build, my mortgage on the shell would be due each month and I will have 0 income until I can build out and rent at least 1 apartment (assuming the city would be willing to grant me a CO for each apartment completed, instead of making me build out the entire building before issuing me one CO for the whole property) and find renters willing to move in at a discounted rate until the construction is over and they won't have to deal with the daily noise.

I recommend setting up keyword alerts for each area as they are discussed in the forums daily with advertisements posted in the BiggerPockets marketplace hourly.

I contacted a realtor, talked to her about my goals and requested to be put on an auto mailing list.6) I created an excel document that I printed out and have tasks to complete every day (including running daily deal analysis!)

I disagree agents are flat out lying about ownership on a daily basis. 

And of course - what part of town do you actually want to live in on a daily basis?
