You know what I find interesting. If you look at book values of stocks you'll find that they are "overpriced". However if you look at the book value of low income housing you'll realize it is at an extreme discount. Houses will sell for 30-40 k. In order to build these houses will need about 100-120k. A good opportunity ?
Being a slum lord really doesn't appeal to me. The reward of monthly rent isn't worth the risk of being shot.
