HelloI’m looking for a software platform that helps landlords manage their leases.

 If I could do it over I would definitely buy a four family I started with the duplex then a three family and then a four family and I now do 4 families and larger if one person moves the only missing one fourth-year income versus a duplex where one person moves are losing half your income plus with the price point on a four family your depreciation and you’re write offs are larger and later on your net worth is higher

So putting other properties in your personal name you are still able to write off all the expenses for the extra properties?

If each co-owner has an undivided half interest then have the co-owner who wants to sell, write out a detailed affidavit with any available documentation -listing all of the expenses that each co-owner has paid for mortgage, taxes, insurance, maintenance etc, during the last three years (or whatever your local statute of limitations is to file for unpaid debt). 

If you have changes, like a rent increase, write them in.

I’m searching for a software I could use to track and record my Virtual Assistant so I could listen to their calls.
