@Renee Z. Congrats on getting your credit score up.
However, I don't mean to sound like a negative nancy but there is something that really concerns me. You are buying another home with out enough down payment money (at least this is what I am understanding from your comment about having your father-in-law lend you the down payment). This is very scary because not having enough in savings is the one thing that wipes out most real estate investors. What happens if your condo tenant stops paying rent? Will you have enough to pay both mortgages, eviction procedures and potentially repairs after they trash the place? What about if you need to replace appliances, HVAC or have major repairs to do (on either properties).
Sure, buying more properties is an awesome goal and you have the right mindset by looking for something with 2 units so you can have subsidize living and save more money. Right on. I would just hate to see you get in a tough situation and lose your butt off (trust me I've been very close to that a couple times).
Aside from that, stay motivated. You've got this!
