Is it just as easy to terminate a MTM lease with an undesirable tenant as it is with a 1yr lease? 

(It sounds like the rest of the items, while undesirable, are not sue-worthy, so to speak).So ask yourself this -- you have a landlord who is basically not doing what he's supposed to from your vantage point, and you want to sue.

Something like: "We do not rent to lawyers, law students, drug dealers, <other undesirable but unprotected groups>" How do you phrase your rejection letter to a lawyer and what if that lawyer is also a member of a protected class?

Yes, good lots are hard to find now, there are some around 150k, but are undesirable sloppy lot.

As the saying goes: an ounce of prevention is worth a pound of cure. 

If you think the neighborhood is rough and generally undesirable, that is likely the kind of tenant you are going to be able to attract. 

I've seen everything from pit bulls being picked up from the pound and aggressively slamming against a neighbor's window to attack their chihuahua on the same 1st day,  to people claiming to need four ESA's, even ESA pigs.I know that designating a building as a no-pet building can lead to playing the hyper-allergenic tenant vs.

When working with an agent we speak their language and are doing a lot of the work for them in getting the comps and justifying the price...so if they can do their job quicker, they can make more money since they can pound out more reports.But the most important reason is that on anew open market sale, the market has determined what the property is worth, so there is a built in risk control by an open and free market.

There is a good lesson that an ounce of prevention is worth a pound of cure (i.e., doing everything before they move in). 

But, the chances of getting a homeowner to respond is near zero because either the property owners have Plan B, C & D already figured out, or they have so many other investors pounding on their door you have a slim chance of making any kind of deal.
