This will help you see if your land cost and build will pencil in.

I wouldn't want a property in Hillside if you gave it to me for free. 

There is no cost to join.

What is the cost difference between replacing only the garage vs whole roof?  

You just need to close correctly and legally.We have several information and instruction documents we send out for free to anyone wanting to learn.I will reiterate -- no fight intended -- just advising what we have seen, done and developed over the past numerous years.Stay safe out there guysAlan 

How much free time do you have and how much more investing could you be doing with it?

I see many town home new builds have this feature but likely because it allows higher density/lower cost of land since many lack yard area but the rooftop allows an outdoor feature. 

Costs are very high, but uncovered spaces aren't renting for that much (we're a frequent visitor to New Smryna Beach btw). 

Most claiming to cover closings costs/sellers cost.
