If the ex wife is not paying the taxes, what else is she not paying... meaning a good title search for outstanding liens should be done first before proceeding.

Rental income has been outstanding ($400 mortgage and $1750 rent)...Now I'm refi'ing to pull out $100k for my next deal.

I would say it's in-line with the surrounding area as well.Mortgage interest paid(year) - (interest paid) - (outstanding mortgage principal)2019 - $7,233.55 (175,077.22)2018 - 6,891.92 (180,120.01)2017 - 7,081.24 (184,835.33)Current principal balance (169,041.00)I'm not really sure why 2019 interest spiked +$341.55 but that is something I am going to look in to because that shouldn't be the case.

The loan requirements are the same as a traditional FHA loan underwriting (owner occ, 3.5% down at 580 credit or better, Mortgage Insurance, etc) except you can use up to 75% of the rent roll to lower your DTI ratio, and you cannot have any existing FHA loans outstanding unless 100 miles away from subject property.The 203K loan has a lot of upside but is quite cumbersome to navigate.

Our weather is amazing, the people are outstanding and the food is the best in the world.

People have been talking about a "crash" for years now, and wise folks who bought anyway have now enjoyed that many years of outstanding appreciation in Denver, while tenants are paying down their loan principals. 

Tenants still aren’t of the best class, but cash flow is outstanding there.  

A neighbor complained and the local police and state police arrested and removed him due to another outstanding warrant.

Since then, I've paid $550 in fees, and probably accrued over $1200 in additional taxes (total probably ~$3200 outstanding).

Fortunately, there're many other outstanding tax pros who you can find here, including the 3 of my colleagues who replied earlier.
