I would speak with a lender, but the price of the home isn't what would affect whether or not it can be financed. If the home is in bad condition and in need of repairs it can be harder to obtain finacing. Maybe whoever told you that meant the homes you are looking at under 100,000 would be harder to get financing on.

For instance if the home needs major repairs it will be hard to do FHA or VA financing as they have strick rules about the condition of the property. Coventional loans have restrictions as well and if the property is in total disrepair it may only be possible to buy with cash. It really just depends on the home and the type of financing you are looking for along with your credit.

Never heard that one before. Maybe now with what's going on with mortgage companies they have tighten requirements but it's really your ability to borrow that matters.
