Any time I hold an older house as a rental I just REALLY pad my rehab costs and I factor in a higher maintenance cost. I flipped an old farmhouse a year ago and once you start tearing those old houses apart... replacing things isn't as easy as you think. A lot of new investors also make the mistake of thinking their expenses are: taxes, insurance and utilities. If you are going to hold it as a rental and its a single family home- tenant should be paying all the utilities. But as the landlord, you will have vacancy and maintenance expense. And with an older house you should be factoring in a higher maintenance expense because the home is older (stuff cost more to replace and there are more problems). So, for example, in my area I use a 5% vacancy and 10% maintenance expense. (% of monthly rent). If I buy a really old rental that I'm going to hold (old plumbing, older heater, etc). I might factor in a 15% or higher maintenance expense depending on the age of the building. So basically.. pad your numbers :) And you should be fine. It is hard to say w/out seeing the house. My suggestion if it is vacant ... would be to take a contractor with you when you do a walk through. Even if you have to pay them something for their time. Get their thoughts on the age of everything, upkeep, maintenance, etc. Even when I think I know... contractors have opened my eyes to many things I didn't catch myself... even with experience.
