One of my investment properties had two, separate plumbing issues (wthin 2 years of one another) that we filed claims for.

If it were mine, I'd put in a very small rental office, just a half door walk up with a room for a desk and 8 tall file cabinets (and a half bath for management use).Sleeve A/C and electric heat the office with some benches out front for residents and wanna-renters to sit on.And use the rest of the place as rent-able units, except for maintenance storage areas. 

I am going to file a police report when I return (I live in another state).

Personally in partnerships I've had a lawyer draft the partnership and it gets filed with the LLC we created. 

If you can't find what you're looking for, try the BiggerPockets' FilePlace: https://www.biggerpockets.com/files It contains hundreds of files such as ebooks, checklists, and spreadsheets for real estate investors.

If your parents did indeed receive a satisfaction of mortgage letter, it would have been filed with the County.

so the costs for the court, the extra costs for the PM to file etc etc. but you cant write off lost income. sadly.  

Even if you sell the land the developer will want to go thru most of the process before he settles on  it , unless you come to other terms . 18 acres down the road from me took 10 years to complete the paperwork from zoning , engineering and county approval for town houses, it was just approved and now an appeal was filed , that sets them back 6 months .

I ended up filing a case with my Landlord's insurance who will be processing the case; am I required to provide my tenant with any of this information?

How long did it take for you to get a court date since you filed the case?
