@Frankie Paterno In most places you will likely find that your $1.2MM will go much further with existing built as opposed to developing.

I have other existing consumer products.So I would outfit the RV with Solar and Starlink to provide power and internet at all times. 

If I am wrong, then please clarify what is and what is not allowed in response to someone stating that they need a CPA.If I am correct, then let me tell you that these rules are enforced very inconsistently, and there're a few people who have been committing these violations repeatedly for months, seemingly without any repercussions for this behavior.

However, lenders often add their own requirements, and many interpret the “intent to occupy” as a longer-term commitment, sometimes defaulting to the 1-year rule as a safeguard. 

At this time the interest rates may make keeping your existing home a better option than times when rates have not risen as substantially.  

For those holding hope they will fall and save existing deals, don't hold your breath. 

They are billed as "a scientific approach to single-family rentals" and use "institutional grade property management," which usually means they are a tech company in real estate and likely either don't have the existing property management relationships in each area or you chose an area where they don't have enough units through Roofstock for the PM they chose to care.

The foundation was already approved, permitted and finaled years ago for a 3400 sf house, and its solid and I won't be building directly on the overhang edge; but rather back away from the edge a few feet to prevent any load issues all the weight will be on the longer sides of the existing footing.

Also consider all lenders will require to review your insurance when underwriting a loan and it's likely a violation of your existing loan documents to let the properties go uninsured even if they didn't require insurance escrows. 

In a rare case, it could be the second lien that is forclosing meaning the first lane still exists, and you would be on the hook for that.
