The appraiser determines the market rents with a survey (form 1007).

The land was deeded and is part of a larger lot that needs to be platted, surveyed and sub-divided.

Call a survey company and schedule a appointment to sit and come up with a game plan, they know city code like the back of their hand 

I think the mistakes make the better information.I purchased a lien on a property in Coal Creek Canyon area, in Jefferson county, Colorado and it turned out that the property doesn't actually exist, or fully exist as the survey that was originally performed created questions about the boundaries with regard to another survey. 

The second home will need to be surveyed as its own square on that land, with its different home address.licensed MLO, be happy to answer any other questions my man!

The survey found that:89% of buyers desire Energy Star-rated windows86% of buyers desire Energy Star-rated appliances81% of buyers desire Energy Star rating for the entire home77% of buyers desire energy efficient lighting77% of buyers desire triple-pane insulating glass windowsThe chief motivation for these sustainable features is the potential savings they offer in annual utility costs.”https://myhome.freddiemac.com/...

Appraiser can do a 1007 rental appraisal survey which is always going to be lower than your lease, then 25% haircut minus PITI+HOA. 

Just wait for the survey, than have at it.  

Read your contract and you can see how it works in your state and what is agreed to, all your answers are there in the contract.As Charles mentioned what if a survey finds out someone's driveway runs across your property? 

They only ask the big multifamily, and they only survey apartments.
