My company does some short-term, but we specialize in mid-term rentals (1-3 months).

I am a full time real estate agent that specializes in luxury and residential - you never know how our two worlds could collide.

The goal is to get the loan and agreeable terms, not have it called something special.

In fact, there're several "layers" of restrictions, including "at-risk" rules, basis rules for pass-through entities, hobby rules, new (as of 2021) "excess business loss" rules, special rules for Section 179 and business interest, self-rental rules, vacation homes rules, and more. 

The initial effect on mortgage rates was a subtle increase in long term bond yields, however in comparison to earlier this summer residential and commercial mortgage rates are down considerably.For example commercial lenders were in the 7%++ range just a few months ago, and recently are as low as 5.5%-6% and falling.

Timeline: Start the process early to avoid issues with your hard money loan coming due.You should reach out to lenders who specialize in investment property refinancing.

You cannot charge one dime more nor a "pet fee" because service animals are NOT pets.If the applicant wants special features such as a wheel chair ramp, etc they MUST install that at THEIR expense and you can require them to bring the property back to its original configuration at the end of the lease at THEIR expense. 

Sure, you can make your unit extra special through design or amenities but when most of your competition is similar in size/shape, those extra items can only warrant so much of an increase in ADR. 

This is basically you paying into a bond that will pay damage and lost rents if you are unable to the landlord but this isn't a collective of money pooled together for the common good. 

This is specialized commercial.
