In my mind sub to is for short term .. long term rentals is very problematic for many reasons. 

You can do this as a rate and term refinance with no cash out, or a cash out refinance. 

IDK pets can certainly do damage but with a decent long term tenant I tend to want to preserve the relationship.

Hi Robert,Given you are looking to buy another rental (long term), a cash out refinance on the existing property would be a good play here.

But, it is bad for landlords, long-term.

I’d offer to sign the form if I was allowed to cross out everything between brokerage firm and during the terms.

Just in case.Ultimately whatever correlates with your future plans but a solid way to build long term wealth.

To throw a wrench into things, if we were talking about real property/structures that were being short term rented, it's possible/likely that your depreciation period would be 39 years, not 27.5.However, a vehicle - which is what an RV is, regardless of how you're using it - is 5 year property.

Of the many strategies I've looked into, House-hacking and short-term rentals piqued my interests. 

If that's the case, you should be able to rate/term refinance at ~75% LTV with a DSCR loan, and with some interest-only basis, your payment will go to ~$850 (based on ROUGH pricing TODAY).
