I like the extra money I make when a realtor brings me full market price but i always budget to give up 10% of the full market price at closing to realtor and buyer closing costs.  

Then CapEx will come along and eat your lunch in the long haul since all this time you were only budgeting 10% and didn't realize that it does not scale with gross rents and when the roof goes out it costs what it costs to replace; the roof does not know nor does it care what the unit is rented for.

I am just starting out and have a limited marketing budget of 1000$ a month max and that's pushing it.

The numbers will work but you may need to add more to the budget for turnover, lost rent, and damage as this area has a reputation for all of the above.

You give me a C class building from the 70s in a AA area and enough capital budget and I'll make it an A class building (probably won't make money off of it due to the magnitude of work it'll need but tha S not the point). 

You're good at budget analysis on any particular property deal, apply similar principles to the family budget!  

We are looking at our first flip - ARV is $ 145-150 K, contract is $95,000 we are estimating a repair budget of $25,000.  

I assisted a lady with a personal budget this week.  

My budget is $75,000 and would like to get at least two properties with this amount.

. $116K, that includes budgeting for capex ($30/month/unit), a 3% vacancy and a 5% property management fee.
