The Detailed Engineering Cost Approach is generally used for newly constructed commercial buildings.DETAILED ENGINEERING COST ESTIMATE APPROACHThis approach is very similar to the Detailed Engineering Cost Approach, with the difference being that if there aren’t records for specific costs, an estimated cost is used rather than the actual cost.

I have been trying to research the least expensive way to keep my records until I build my real estate rentals more. 

I feel like a broken record how often I say this lol but we have cashflow, affordability, growth, and appreciation.

Look at their rental history, the conditions of their previous residence, and ensure they have a good track record with past landlords.

that doesn't seem ideal - i think people should build up a track record before borrowing private money and putting it at risk.  

"I'm willing to cancel the eviction so it doesn't reflect on your record if you vacate on x day and pay x toward your outstanding balance"Most tenants are unaware of the long-term consequences when they have an eviction on their record.

It's very simple, here is the header for one sheet:# Of RentalsAddressDate BoughtYear Roof was put onCost of PropertyValue of Property 2017Value of Property 2021TaxInsuranceMortgageMaint/HOAAC FiltersRent Per MonthThen I have another sheet to keep track of any expenses for the year:# Of RentalsAddressCityJanFebMarAprMayEverything is very organized on these two sheets for the CPA every January.

Everything is nicely organized and labeled.

I do  think your point about having an eviction on her record is a bit of leverage though.  

Basically, she uses her good score and no eviction record to lure landlords and then have someone else lives at the place.I am in the process of contacting others and filing a police report.
