I had one lady I visited who had all of my marketing materials from the last 18 months in a folder - some folks do actually save these things.

Guys, here is the final breakdown as requested by @Phillip Le :ACQUISITION (for purchase price, closing costs, lender costs, escrow costs): $434kREHAB (LABOR + MATERIALS): $102kREHAB TIME: 10 WEEKSHOLDING COSTS (MORTGAGE, STAGING): $16KSALE PRICE: $660KCLOSING FEES (Escrow, Taxes, Commissions): $58kPROFIT: $50K

.$200-225 per square is the going rate around here for material, labor, haul off on a single story walkable pitch and that's for tear off (one layer) and replacement with dimensional shingles....good luck!

Raking  with a metal fan rake. not sure if the shop vac will do it but it is worth a try.

Can you give a breakdown of the cost of material and labor.

Going to take a look at Home Depot and Surplus building materials.

I used to work on Hotels and what we would do between rooms for the most sound proof wall assembly was have two layers of gypsum (mostly for fire protection) on each side and then stager 2" metal studs (4" thick wall total) with insulation wrapped between. 

As stated earlier in the thread, primer is less costly than finish paint and you have the same labor and material quantity 2 coating with the paint or priming and top coating.  

Yes - they are excellent. 90%+ of the material is relevant to any rental property in Wisconsin.
