Hey Brett,
For me to even look at a deal, I use a standard 1% rule. i.e. 1% of the purchase price is the minimum rental rate. At at $25,000 purchase price, minimally you want $250 in rents - which you obviously have. Typically, if there are no repairs and the property is rented out in a decent area, 1% should be a break even cash flow. What's throwing off your numbers are 1, the taxes and 2, the monthly maintenance.
The taxes are mentioned in several posts above. As for the monthly maintenance, if there's no repairs, then your cash flow will be over $100. Of course, there are typically repairs in any rental property. A couple of ways around this is to have a repair clause in your lease agreement. i.e. see if your tenant will agree to cover minor repairs that costs less than $50. So if a light bulb goes out, they replace that etc.
In this market, what works best is actually a lease/option. If you can buy the property for $25,000, and it's worth $68,000, then sell the house on a lease with a purchase option.
There are several benefits to doing that. First, lots of people have bad credit who cannot qualify for a loan in this economy. So you can find someone who has a solid job with no credit to lease out to and give them time to repair their credit. Second, you can get a higher rental rate. You can charge $600 or even $650. Third, you can (and would) charge an upfront consideration payment - typically not less than 5% of the purchase price. So if it's worth $68,000, sell it on a lease with an option to purchase for $40,000 - $50,000. You double your money in a few years and they get a fantastic deal - win-win. 5% of $50,000 is $2,500 which is 2 years worth of your maintenance fee (only it goes right into your pocket). Next, because they will eventually purchase this, you can put in your lease agreement that they will cover all repairs under say $500. Any major repairs which may be needed for any reason, you would cover. This also saves you on property management.
Basically, lease options are great way to go in this market. Something to consider.
Either way, it looks like a solid property with potential.
Good luck.
