It offers a good amount of accurate data but it’s not always current.

I don't have any data but my gut feeling is that it's because there's a lot of $ available to borrow for a mortgage. 

I think you should look at other things in terms of your negotiation, a washer/dryer is minuscule in comparison to an inspection report, comps in the area, recent sales data etc.

If I was not an agent that is how I would get my Data.

I recommend latex type to homeowners that live on expansive clay soil so movement in slab is reduced and doesn’t transfer/pop tile floors.  

Transfer taxes in most states (not sure about RI) for smaller buys and sells are paid by the seller, so you wouldn't have that cost twice.

If I were to continue doing deals like this would it makes sense and an asset protection structure point of you to transfer my own personal equity into that of another LLC?

There are munis and public utilities that impose some serious fees and repairs when title transfers.

If I purchase a home owner financing for 6 months ballon remodel it and get a contract on it when I transfer it can it all be done at one closing to avoid 90 flip rule requirement fha only will finance properties that have not been transfers in prior 90 days.

I suggest you Google "APOD", which stands for Annual Property Operating Data.
