Tags need to be on the mobile home then the data plate inside indicating model and specifics on manufacturer etc.I've found it difficult to finance just the land too with the home on it. 

I have worked with all of them on multiple projects that I have designed so I trust them to do good work.

It was originally designed as a second home for myself.

@Rob Shah,use Rentometer.com or BP Insight to have an idea of what the property will rent for.If you don’t have access to either then use 90% of whatever Zillow Rent Estimate is for example, if Zillow says it will rent for $2000, then 0.9x$2000 = $1800 will be the most likely rent.That been said, the best comparable is the one you get from an Agent because they have MLS access with a lot of data that will provide you the best result.Goodluck

I am finding a lot of data from 2019, but the last couple years have been rather different than the trend from the past decade. 

@Vincent S.There are two credentials that most sophisticated tax professionals have.CPA(Certified Public Accountant) & EA(Enrolled Agent).CPA designation is the more prestigious of the two.There is no designation to indicate that he/she is a professional is 'real estate tax'.I would have a casual conversation with the purchases that you made and how the rental is performing. 

Yes,A builders Risk policy is a specialed policy designed for a building under construction. 

This is someone else data.

We also buy quite a bit of liability coverage and umbrella coverage.That having been said we do always question how replacement cost is computed as underwriting is often doing that from 1,000 miles away on a data base knowing nothing about the property and they have always been willing to adjust a bit when we have felt it appropriate. 

Finding someone to do this for you could be relatively expensive, so best you contact the city, find out the process and handle yourself.Once you have city approval, you can then hire an architect to design the new structure, or buy plans online.
