Keeping in mind the cities where prices are high, the demographics undesirable, or new businesses or homes being built etc., what areas are worth (or not worth) an investment property?

We had a tenant turn our yard into a mud pit for girls to wrestle in. 

He got thoroughly dragged through the mud on BP on this one.the NPN space that gets those re performing then sells the notes as performing notes is a little the same.. not quite but the risk to the new note buyer who does not understand the note business is quite high..  

Someone said I can sand them down and apply some type of filled maybe mud them and then paint over it.

Don't forget to add that certain areas have MUD taxes.

I also wonder if I need to work with someone maybe less established who's willing to get in the mud with me for deals. 

Clear as mud?...

That means you may have the County suing, School and MUD may not, but can later. 

@Markus CochranAll you would need would be the tenant going to the media with that story and even the hint of a shred of proof, and your name would be mud as a landlord where you live.

And that's new information to the seller, you can improve your negotiation position because they are then required to disclose to future buyers is my understanding.On to the technical and again I'm brainstorming out loud here....I have ZERO experience with mud jacking as a permanent solution to slab heaving issues - however I would wonder about the feasibility of this as a 'roll the dice' kind of solution (good money vs value trade off) ...if you buy.One possible solution may be to jack the house and repour which I don't know much about how the bottom plates/wood structural would be tied into the slab - but jacking the house and re pouring sections or all of slab would be an incredibly costly endeavor.
