Keeping in mind that this advice comes from someone who doesn't necessarily trust property management companies or the quality of their services. 

Now, I need to know the exact usable space, wetland delineation, water & sewer hookup cost, mitigation banking, cleaning up the trees, construction cost as exact as possible.

Thanks Wayne - my wife was suggesting that route also, do you think it is worth it to clean out first?

They'll run the serials (if they have serials) and check if the firearms have ever been used in a crime.If they're clean and clear, I disagree on disposing of them. 

I provided a gift basket which contained the following: (call me crazy) Laundry Basket (new to hold the items and because no washer/dryer in unit but onsite)Small Tide Pods package (to get that starter load going)Cascade Platinum package for dishwasher (probably a years supply cost like $10 at Target)Swiffer new for laminate floors to keep clean ($20?)

The rent needs to justify being able to maintain a clean functional rental though so do that analysis as well. 

We agreed on a price, I have a one page purchase contract, I contacted the title company and started the clean title process.

Large flat walls are cheaper than small areas with lots of cuts & corners.It will take a small crew about 7-10 days to hang drywall, tape and mud, then let it dry a day or two, then sand, mud again, dry again and sand again, finish and clean up.

Once the property is foreclosed on, the title gets wiped clean. 

My fear is that he leased up the building with low quality tenants and doesn't want me to review the tenant screening materials.
