Property Management System, in Excel multiple buildings

Property Management System in Excel, multiple buildings Hi, I am looking for a programmer who is able to program a property management with multiple properties, that does the following. Unit Payment Date Amount Paid Account Type (Ru, Mu, St, Deposit) (please add Deposit) Auto Calculated Fields: Name Rent Type Rent Amount Rent Start Date (Monthly/ Weekly) Rent Due Date Balance Pending Amount Adjust Balance Address I will enter all the data in 4 boxes These data on the bottom will appear automatically. Example 1: When I start entering 1 year old data, If there is no name in the Name box I will enter the tenant’s name, starting that date, payment date, when I entered the new tenant’s name, it will be permanent, after that date, whenever I enter unit number, same tenant’s name will appear automatically in the Name box. Same principal should apply with other fields also: Rent Type: Weekly/Monthly data box, If I enter the data in this box, it should save it from that date on and use it after that date for calculations. If I change it in the future, it will change from that date on. Rent Amount: same principal, it will appear auto unless I change it in this data box, and save the amount from that date on. Rent Start Date: same principal, first I enter the data, then it appears auto, but if I change it here, in this box, it will change from that date on. Rent Due Date: same principal Balance Pending Amount: It will appear auto according to calculations Adjust Balance: I want to add this box to adjust the balance pending in case I adjusted their rent balance, if I lower tenant’s remaining balance. In this box amount is, Balance Pending Amount, from the other data, but if I change this data box, next time, next payment date, it will calculate according to this amount, not the Balance Pending Amount box data. Address: will appear auto
