Logistically it's challenging since we don't have much time nor a truck to transport plywood to the house.  

Remember, most are unlicensed and brokering without a license, have no accountability to state boards, operate as fringe operators skirting laws, may be correctly called public nuisances, have no insurance, etc.

I tried looking it up in the public records but they dont show the downpayment.

my understanding is that brokers typically first shop deals to  investors whom they've had previous dealings with, then to other brokers in-house, then to the general public. 

The final sale price will be public record and being a real estate agent is highly competitive trade.

That new industry is transportation and warehousing.  

You can either find the closest public parking, rent parking elsewhere, or simply not park a vehicle. 

These leases should also be recorded in the public records.NNN leases are commonly used for commercial transactions.

@Joshua Tikal College rentals are not something we specialize in but the experience I have had from managing thousands of rentals over the years is that everyone starts out wanting to provide good housing options for the general public but lose sight of the fact that this is a business and please run it that way.
