I stay away from secondhand and thrift places, and make friends with contractors that get huge discounts at supply stores (sherwin williams, plumbing wholesale) Sometimes buying in bulk and selling what you don't need is a great way to meet people doing the same thing as you. 

I will structure my deals to have a clause where investors want to hold for a longer period.

We don't require a contract for each door unless it is set up as a condo. 1 months' rent is a little steep but it will depend on the local commission structure.

The "other structures" were only 10K, while everybody else goes by 10% of the coverage (on 340K coverage of the main structure, you get 34K other structures).The ugly part - much higher deductibles: $5000 general deductible and 3% wind/hail deductible (on a 340K coverage it comes to a whopping $10K+ deductible...makes you understand their "largesse" on unnecessary higher coverage...if they know the rebuilding cost is 250K, they can give you 300K+ because they will not have to pay more than rebuilding cost, but it pushes the deductibles higher).We concluded:1.

Admittedly, this is not standard, and when installers arrived they said they can't and won't do it)Supplies not arriving on time and impacting scheduling.
