I use this a lot for location based discussions: http://www.biggerpockets.com/alertsRead Beginner’s Guide: http://www.biggerpockets.com/real-estate-investingI find the calculators are very helpful when analyzing deals!

QUESTION #1: I believe I have a great deal (per the Biggerpockets 'Rental Property Analysis' calculator).

Finally, BP has various tools available to help you analyze your deals (rental, flips, wholesale, etc), feel free to use them: https://www.biggerpockets.com/investment-calculators Please let me know if I can help, and best of luck!

Vacancy isn't included in my expenses because it's its own separate thing in my calculator.

I've used that calculator I just didn't know if it would give me accurate numbers based on me living in it prior.

Would i use a PDF from the calculators?

Here is my question- when I am calculating all the variable costs that go into cashflow (repairs, vacancy, CapEx), should I be planning to add those amounts to my reserves every month once I have a tenant (if nothing goes wrong and I don't have to spend that money) or do I just maintain a certain reserve balance and consider the rest of it to be profit once I have a solid reserve balance?

With a snowball calculation.

I’ll PM you I have a loan calculator so you can look at the numbers.  

I would look at this as an investment first, so calculate what the true NOI is if you rented out both units, have management fee, reserves, etc all calculated in.
