Hello, I want to use my equity in one of my SFRs to purchase a short-term rental (I currently have 8 LTR) .

Rahul, I have about 10 you can talk to. you'll also want to have an equity partner with new build experience so you can get the best terms. most of ours are national lenders. we doing joint parnterhsips for new builds and take a small interest in a single purpose entity for example:Rahuls New Build LLC (95% owner)Pink Development and Construction LLC (5% owner, no voting or distribution rights)Take title to "Miami New Build Limited Partnership LLC" which is a single purpose entity. 

I think of it like a long term rental that has the address listed all over the internet.

So long term, in my opinion, I always take higher quality location SFH over multifamily house hacking but if the latter is the most and easiest access point into REI then definitely roll the dice.

I purchased a short-term rental property a couple years ago that requires crossing another landowner's property for access.

Long term Ive been looking close at Mesa.

The program provided valuable insights into market analysis and helped me develop a clear vision for my mid-term rental (MTR) strategy.One of the things I appreciate most about the program is its inclusivity.

HELOC better used for short term, ideally for under a year.

In my opinion the best use of a HELOC is for short term needs like a credit card.

Something like damage to flooring might have been noted then.As for useful life (this is term used in California law), your PM is correct in taking the useful life of component into consideration.
