We had one incident where a tenant got divorced, mentally fell apart, received a dog as a gift and kept it locked in a bedroom all day.

Any one close these?

What are some of the best techniques to shut down those who protest against landlords who want to charge high rates in a neighborhood facing gentrification?

I own and operate a property management firm in Chicago. 

4-Plex details: -currently occupied-estimated sale price 265k-ARV 400k, and 4k/mth in rentBackground on me: -I have an LLC-I own 4 single family rentals-each has around 70k + in equity-all cash flow well -credit is 800+ with adequate income.

But before we go through to put together something more specific on the property so he can see all the numbers.

I'm looking to whole sale now in the Los Lunas area 

Tile all the way @Marc Shin.

Allow a pets and I think you will have a great spot.Would adding that extra space/ spending that money be reflected in an appropriate increase in the property value too?

A few recommendations - learn as much as you can from books, podcasts, and attending free or low-cost real estate investor meetups in your area (in-person is best).
