@Catherine Emert makes a great suggestion on put up an note on the front door.   

But my hope for you @Onan, is that you will grow your business and face these pains where you’ll need to be able to ask someone to dance ... an not have to wait to be asked.

What has been the appreciation of values in the last few yearsOn a map, annotate where are the A, B, C, D category areas (according to real estate agents)What's the situation with titles in the area?

I also have a spreadsheet for each property listing each associated account, to annotate purchases that aren't super clear from the bank statements.

My concern is that this will tie up all my cash and credit into this deal an not give me much opportunity to borrow against it for following deals.

To further streamline my accounting and keeping a paperless office, I'm looking for a solution to add a stamp/annotation to an existing pdf invoice/file. 

I was curious if any multi-property land lords have a good system (or suggested products) for keeping expenses straight and annotated throughout the year for their different properties.I have separate LLCs and bank accounts for each property, however when I go to export and classify most of my expenses for the year, I'm finding that I forget what some unlabeled (or hard to decipher) expenses were, and thus may be classifying them wrong.I'm looking for something like Quickbooks, but that can handle multiple LLCs/Bank accounts, because as I understand Quickbooks requires different user names for different businesses.Note: I have tried Stessa (and honestly, what it does is what I'm looking for....) but because I use smaller regional banks, the connects to the accounts have troubles several times a month, and I end up having to go back and manually import transactions anyway, so it ends up taking more time than it saves me.Thanks!

@Ronald LambertThat is an note investment so it will work.

I was inform by my PM that a tenant is moving out an not renewing their lease.

The value of the property...Why is it important - because RE is an not a liquid game, and while coming in is easy, leaving can be hard.
