Hillside duplex

[Hyuma Leland]

Hi BP,

I am in escrow on a hillside duplex in a popular area of Los Angeles, numbers wise, the place is about break even with my long term buy and hold strategy, but will allow me to build equity, credit, and take some tax breaks. 

Does anyone have any experience with hillside properties? what additional foundation, drainage, retaining wall issues should I be aware of? Do you typically budget additional expenses? Any rough estimates on build costs for hillside drainage to prevent land erosion (1000's, tens of 10,000s?)

Thanks!
