Your montly income is $1150, but you still have $1302 in expenses.For one, since you doing brrr you still have a mortgage ($125k) as part of the final calculation contributing $774 in P&I. 

I contribute a portion of my commissions towards discounted stock purchases, and they award me with stock for certain production milestones.

@Dion DePaoli any perspective you can contribute is appreciated. 

Other people want everything proportionate vs capital contribution.

Check their rates, lease fees, lease renewal fees etc.Do direct deposit of your rent collection and contributions to your PM for repairs from that bank account you just opened and never touch the income as you save for the next property.Do a spread sheet on all your properties as you accumulate more to keep up with passwords for log in to lenders, PMs, insurance, etc. keep track of cash flow, property taxes and insurance (the fluctuations of these benchmarks will give you the information you need to make decisions on raising the rent or not.

@Mary M.Any appliances you have in that building will contribute to your kilowatt hour usage.

if you own the land out right and contribute it you bring a lot of value with the whole package.if its just your idea and no money and no risk.. then the money is entitled to the majority of the upside ..finding people to do what you described is not that hard and they will do it fee based.  

You and your wife can each contribute 6000 a year for a total of 12,000.

Been making my secondary focus primary the last 2-3 years by maxing out my 401K and contributing my tax return to my Roth IRA; so would like to contribute my income/savings directly into real estate).
