After long-term appreciation?

Alot of factors to consider in terms of rates but Id say par for the course in the conventional space high 6's

They would like to fully furnish the property and renting the house either long term or mid term or STR.

Cashflow day one and appreciation over the term.  

Or could you demonstrate that it was always a short-term rental from the beginning simply based on your listings + the several guest stays in the following year(s) during auditWithout specific guidance, I would take a risk-based approach, and call it an STR if the intent and preponderance of the subsequent actions suggests it from the service date.Is there a tax court case that establishes this?

But there could be reasons like type and terms of financing that make this an attractive option3.

Not much new to add, other than this short-term niche seems to move quickly, so getting ahead of the trends is key. 

Most work this way BTW Rates: 9% to 13% (Most Deals are 11-12%)Terms: up to 36 Months (Most Deals are 6-12 months)Fees: 2-4 points(%) of loan amount paid at closing (Most Deals are 3 points(%))Minimum Loan Amount: $50,000 (For loans less than $250,000 $2,500 minimum fee)Max Loan: 65%-70% of After Repair Value(ARV)100% Rehab Financing Available (Require 20% of purchase price down payment or cross-collateral)Closing Timeframe: 48 Hours - 3 Weeks (Most Deals are 2 Weeks)NO PRIMARY RESIDENCES, NON-OWNER OCCUPIED ONLY, BUSINESS AND COMMERCIAL USE ONLY.

It does not answer every question (are they under/overcharging, do they have egregious cancellation terms, do they have silly rights to sell your property, do they have two and half pages of ticky tack fees, etc.), but something has to go reasonably right for a PM to have 95% occupancy or greater on a several hundred unit portfolio, in my view.

Short-term rental loophole and REPS status are the main paths to follow!
