|  Baltimore has an estimated 17 thousand abandoned rowhouses and 13 thousand vacant lots — hundreds of blocks where the majority of houses are neglected. Efforts to rehabilitate these properties are prohibited by absentee land owners who sit on vacant properties indefi- nitely in the hopes of making a profit.
