This is after averaging out the costs of 1) roof, mechanicals, siding, flooring, etc. and dividing by their life span then also subtracting general maintenance costs (handyman type stuff frozen pipes, etc.) you see each year.

This is a good concept, but to translate into a game, you have to have some core mechanic that holds it all together.

You can check at the courthouse for recorded mortgages etc, but there are liens that may not be possible to determine such as an unfiled mechanics lien.

He alerted me to a mechanic's lien on the property for $25,000 (5 times the tax value), which gave me several days panic until a lawyer friend explained that these liens expire after one year unless a separate suit is filed to enforce the lien. 

If I ask somebody how the mechanics of an airplane works, they will start by saying " I'm a broker in Texas"Everybody thinks they are a good agent just like everybody thinks they are a good driver. 

I contacted the city of Edmonton and was informed that moving a mobile home is treated the same as building a new home, and all the following applies:Development Permit ApplicationCombined Building, Mechanical PermitBuilding & Mech Safety CodesWiring Electrical PermitUnderground Service Cable PermitElectrical Safety CodesConstruction Water Rates 44¢/$1000 Construction Value Sanitary Sewer Trunk ChargeLot Grading FeeTo my knowledge, unlike a new home, all we would be doing is reconnecting the infrastructure, and considering that no modifications are to be made to the existing plumbing, electrical, sewer or the lot itself, so do all those permits apply? 

You did not mention any payment issues, have you been collecting mechanics liens with each payment installment?

My wife and I focus on both flips and airbnbs, with "infinite banking" as our wealth storage mechanism.  

There is still some work to go but the heavy lifting is done with the bones and mechanical.
