Quickbooks online could work for what you need.  

you will need to look at the APN of the property and line it up with what you actaully bought. as mentioned the tax assessed value is not an indicator of value. the land could be a utility easement, used for stormwater management etc.

Service would change, though, as the successful experiences of early-adopter customers would demonstrate the utility and superiority of NewCo.

Two months ago we sold the property utilizing a wrap mortgage with a 10% interest rate.  

If the city ever wants to add sidewalks or run utilities underground, those homeowners will be out of luck.PS: I have never seen a juridisction pay to remove items in an easement or compensated owners for performing work in an easement.

The existing mobile also had utilities hooked up with a $17k impact fee credit that I didn't have to pay to the county.

My question is if we are marketing this as land, is more value added from the 2020 mobile home or the multiple utility hook ups?

I just can't find ANYTHING online that isn't from Chris or his team. 

At the current price, adding the additional lots would make them about $30,000 per lot, depending on the price of the additional utilities that need to be added. 

@Chirag Mehta For construction costs, you should be around +/- $100 PSF which would include all sitework, utilities, and going vertical with modern finishes.
