first dont get excited just because its close. get excited when the numbers work.
you need to gather all your information first before making a decision.
check around the area for rental comps and see what the competition is offering. as far as concessions, upgrades, amenities. Like this you know what you can do with the rents. how much to increase them.
once you know that, you have to run the actual numbers and see if you can make your new mortgage payment and real estate taxes or not.
remember that whatever income and expenses the asset has currently, you will inherit.
speak to several lenders and get quotes on how much ltv loan you will get and what int rates.
now that you know what the current rents are, what your expenses are, what your new mortgage is, new real estate taxes and new insurance cost are, you can run your numbers and see if it makes sense. now you can see what your going in numbers will look like and then you can see what your numbers will look like after you increase rents.
make sure to understand all the renovation budget and closing costs you will need and throw those numbers into the mix.
hope that helps
