I am a newbie myself but I have a few things to add.
When you buy a property it has to be a deal. Traditionally a deal is a property that is 70% or less of it's retail value. These types of deals don't come often. In my area it averages one deal a month, and I have to pounce on it quick or some other investor will lock it up. The most common sources of distressed properties are motivated sellers or lenders (banks).
The property you describe does not fit this criteria. It's been on the market way too long, the sellers are not motivated, and you're buying at only a 15% discount.
The major tax benefit of owning a rental is from a depreciation allowance, which in most cases eliminates taxes from positive cash flow.
It seems that you have not really analyzed the rent rolls in your area. Are renters standing in line to get a good rental, or are their a ton of vacancies in that area, for that particular property type. Assuming that you will get a good tenant by lowering the rent is not a good idea. Good tenants come from properly screening applicants by checking their credit, criminal and eviction history.
Please, please listen to some of the real estate vets on this forum like Mike and All Cash. I've only been doing this for two years and have made a lot of mistakes myself, but by reading the posts here and on other sites, as well as further educating myself, I've been able to do some good things lately. This sounds like a very bad deal to me.
