@James Su - Its located on the south side of Chicago which varies block by block.

And, fun fact, if you throw your furnished rental income on Schedule C for a few years (while saving up a down payment using net profits from that business), it's mortgage qualifying income (granted it was a huge pain in the butt the first time I used it, and I know for a fact that not all lenders will go for it) in the event that you're so successful that you quit your day-job (2 of the 3 names I dropped above are people that do not have a traditional day-job).

Also, they must be able to give you a full block valuation so you can see where the bottom and the top value of the block is.

Nonetheless, I inputted my goal to time block 5 days a week from 10am-1115am to prospect and follow up to acquire new buildings.In 13,14 and 15 we where on a buying spree.  

This creates a steep driveway that is a pain to back out of during the winter.

For newer ECM motors, blocking vents can increase static pressure in the system which means the unit's blower must work harder to continually provide conditioned air to the home, thereby reducing the efficiency (and more likely, longevity) of the unit.

However, the sellers have their pain point too.

What does the corresponding block value tell you about the future value of the property in terms of your rent roll?

This is your best bet, and while it may be painful to pay him ANYTHING, it's the easiest.

It's in a C++ neighborhood, can you put a manufactured house with a block & stucco foundation on the lot?
