How much do you currently pay in rent (to a landlord)? Do you have enough space? Will it be enough space in the future? Would this property give you more space for less cost per month? How much of the rent that you've paid over the years will you get back in equity when you move out of your current apartment?
If this opportunity interests you, give me a call at 773-230-9736. I am not a realtor, just the property owner, but I can answer most of your questions, save you over $20,000 buying direct from me, and put you in your own home now.
* Your numbers will vary based on loan terms, down payment, rents charged, which unit you choose to live in, etc.
