Yes actually.

If you have more than $500K of gain (and you both qualify) or if you have more than $250K of gain and only you qualify then you could actually sell and take both the primary residence exemption. 

There are a few reasons not to do a cost seg study: 1. the purchase price on the property was less than $200k. 2.

Personally I find that a red flag unless they have a good reason.

A lot of my tenants don’t want the responsibilities of maintenance which is part of the reason they rent.

DSCR loans won't use your income to underwrite the loan.DSCR loans are based off of down payment, credit score and either actual or market rents so it helps to supercharge an investor's real estate goals and net worth.Here's a bit more in detail about how rates are calculated for DSCR loans:1.

I am hesitant to build anything in that market right now for many reasons.  

How will you know if the letter is from the actual landlord?

With second home loans, the mortgage must be for one unit (I do a lot of 2-4 unit STRs), the property must not be rented for more than 180 days out of the year (limits revenue), must function reasonably as a second home (usually limits out of state investing), rental income will not qualify as stable monthly income (projected AirDNA does not play into your DTI).

I have never heard anyone using them but I would love to hear some feedback on how they actually manage vacation rentals.
