We have a couple renting a house in Minnesota who is consistently behind on paying rent but they end up paying the full rent within the month, staying just out of reach of agreement termination.

its easy for me to get property under contract however im having trouble unloading it most of the time I do land deals and try to find developers which is normally easier than trying to unload the house is there like a trick to building your buyers list do I create a funnel

I am currently drinking from a fire house on everything investment real estate. 

Purchase price: $36,000 Cash invested: $50,000 Sale price: $275,000 Bought a house, fully intending on living there.

I own a house (NW Indiana) that I fully renovated and now have 200k equity in it.

One strategy is to look for a premium town that does not have large amounts of rental houses.

There's absolutely not any federal level housing law on this.  

Why would equity be important when acquiring a house via subject-to?

I'm currently house hacking a property in Raeford and plan on renting it out.

Also, I'm no kid so the idea of house hacking is out.
