If you search Toledo you will find many posts about the zip codes that will meet different goals...personally I keep half my investments in 43608 (with a rant posted about how dangerous the zip code is to those who go shopping without knowing what they are buying)...43608 is the zero-appreciation investment from my stand point because $20k gets me $700 in rent for a 3/1 so I don't really care if I sell the house for $20k in 20 yrs or $5k, I moved $168,000 in gross rent. 43612 and 43613 are the out-of-towner's meat and potatoes currently, pretty hot area and a lot of competition on the discounted properties that hit the market...assume you are putting $35k to get $750-$800/mo for a 3 bedroom house.Those are just my stomping grounds, I support my entire family on those areas (like Buffet, I have my eggs in one basket and I watch that basket).
