I use Mint where I have logged in all my assets and liabilities and it calculates most of this automatically.

In addition, I would have some type of dated, liability waiver written up for them to sign that states in writing that they legally waive all interest in the existing contract that specifically renders existing contract null and void as of a certain date and time and releases you of any and all obligations of said contract.

The main reasons for the insurance are total loss from fire and the liability coverage in case a tenant was injured or killed on the property.

The general area I agree is good, from my research.As others have noted, I do feel the size becomes a liability.  

Most banks cost of funds are generally short term in nature (checking accounts, savings, cds, etc) and therefore the don't want to match long term assets with short term liabilities.

But I've found that the two other most important things that help when meeting a new commercial banker are 1) A personal financial statement which is essentially a personal balance sheet listing all of your Assets and Liabilities and totaling to your net worth. 2) Profit/Loss statements on your existing properties for the last couple years to show your track record.

The best resource I know of is the book "How to Use Limited Liability Companies & Limited Partnerships" by Garrett Sutton.

I wouldnt suggest a real estate agent because at the end of the day their liability is limited compared to a RE attorney and you already found the properties.

Kristin writes builders risk and liability insurance with Erie Insurance which is one of the best policies in the business for rehabbers.  

John I ended with open ended liability on city and state inspections which have since cost me 20,000.00 and obviously improved the property from what I believe was a "as is" sale.
