The accounting aspect is a an additional thought I hadn't heard before.I know some people have used this strategy in an attempt to avoid triggering a re-evaluation of property taxes.  

I am into all oportunities of this aspect.

That is a huge amount of time to research all the aspects that you presented. 

Tools that automate these aspects can help ensure your property remains competitive and that guests receive timely and personalized responses.2.

Are there any specific considerations or legal aspects I should be aware of when making this transition?

On the other side many major companies are investing in Austin so growth looks strong in many aspects.

The income aspect is a little different though, because you will not be able to verify, or they may not show income on their application if they don't have any. 

Now I gotta figure out this refi aspect of the BRRR method.

You can try to use their taxes for verification but it is still difficult, CAP rates will not reflect tenants that need to be evicted.Hopefully, this has been helpful in providing some additional aspects that are unique to CAP Rates and Mobile Home Parks. 

Private financing or hard money is generally used for acquisition and rehab financing for properties that won't qualify for more traditional loans, when speed is a priority, or when some other aspect will roadblock traditional underwrites.
