If you raise the rent and they cannot afford it--they may move vs re-homing the cats (which is tough to do, emotionally and physically).Just my 2 cents.While I agree with Scott about some very undesirable dog breeds, I do NOT find cats to be good tenants. 

I will be actually heading over to Lincolnton today to pick up my lawn mower from a shop over that way so I would be happy to drive by the house and see if it doesn't have any other undesirable qualities that we can not see.

Clearly, this might be slightly higher than some very undesirable places but I am looking to be close to a subway line and not too far from manhattan.

OTOH, if they're building undesirable apartment buildings, or something that's going to create a lot of traffic and congestion it may have a negative effect.You should look into 1031 exchanges.  

There are may perspectives and is still clear as mud to us but we'll just dive in and see where it goes and what we can learn.

Configuration: Two bedroom, three car garage, mud room, etc.4. 

People with dogs really liked it.Maybe it can be either a mud room or doggie wash depending on whether the potential buyer has a dog or not.  

If the tenant is a D class tenant that is undesirable and I think I want to move them out, then I am not going to show a lot of rent increases from year one to year two, because I know once I start enforcing the rules, these people are going to leave and I am going to have vacancies and have to clean up those units and bring new people in.

It's easier on small or 'undesirable' or harder-to-manage properties.

We are sticks in the mud who buy through a realtor and use 30-year traditional financing.
