1. Personally I would stay away from a 1 br apt, your narrowing your renter pool.
2. You must account for your expenses both fixed and variable. Example utilities, repairs, reserves, include management fee even tho your doing it yourself, vacancy, etc.
3. Hammer down on the actual numbers. Both expenses and income. You state the rents range from 1100-1300 which is a big range. Run your numbers with worse case scenario. Check out rentometer .com and craigslist to find rental comps.
4. IMO I wouldn't be worrying about LLC structure with 1 rental. When you are ready you should be asking your attorney.
Let's look at some rough numbers:
Income 1100/month
Mortgage 900/m
Gross 200/m
Now let's take $200/m and subtract expenses....
8% vacancy $88/m
5% reserves $55/m
10% management $110/m
5% repairs $55/m
Already your at a monthly cash flow of -$108 and I left out more expenses because I don't know the specifics of the deal. Make sure you run your deal through the forums before pulling the trigger. Keeping learning and listen to the podcast. You are in the right track, just practice running the numbers on properties. Before I bought my first property I ran the numbers on EVERY single deal on the MLS that was in the areas that I was interested for 6 months.
