At the end of 27.5 years if the building had decreased in value to $0, then you would owe no taxes.

Because that's still their lease and the lease you are taking over, even if they are month-to-month.For example, on a month-to-month tenant, I can serve a 30-Day Notice to change an item(s) on our lease. 

All in all, my rent of $850/mo decreased to $550 after taking ownership considering the rental income from our tenant.

About 3 weeks after I recorded notice of default, the borrower requested to remove NOD because he's doing refinance and new lender wouldn't lend for a house in foreclosure.

They bought so much land it drove up the price of land and also decreased the land inventory greatly.

This is something I've noticed when looking at homes built after 2000ish.

As a matter of fact, the portion allocated to the interest will decrease every month as you are paying down the principle which means a smaller amount owed = less interest due.

I would also like to evict him from my building for this behavior, but fear that will only increase the threats/violence as soon as he gets notice of this.If I file for a protective order from this tenant, what becomes of him and his lease?

I've been noticing that pricing is getting higher and higher in some cases same property asking price doubles within the days.

Can't help but notice that like 99% of MLS providers' initials end in 'AR' for Association (of) Realtors® i understand ethics requirements and good for the community and such, but arent even those intrinsic to state license issuer, not commercial brand?
