Seriously, no one looks at a girl and think "damn she's an easy 10.....CAP.

Close the cap and lid.For a week keep putting adult dog kibble in the tail pipe.  

But I want to set money back for ST cap gains tax, pay back our personal finances for expenses covered out of that, etc.I guess the short question is: What all costs get taken out to determine if you have a profit or left money in the deal?

This is also why many people cap out at one or two properties.Due diligence with your own investments, systematizing it, and treating it like a business will help you scale much more efficiently

You may want to buy 12% cap rate mobile homes in OKC, you may want to flip land in Massachusetts, you may want to wholesale in NJ, you may want to move to Florida and house-hack a 4 unit. 

My wife and I also understood the fact that we were putting our primary residence at risk and made sure the deal could pay the mortgage, HELOC, vacancy, cap ex, maintenance, etc, and still cash flow positive.

Ask your lender if it is adjusts to the current market rate or if there are adjustment caps (meaning it can only adjust by a limited percentage per adjustment period).  

The downfall to this is that the overall market rate for rentals is essentially capped at the rate of which DoD pays service members for housing here (most single family rentals are in the $800-$1200 range)With this being an active duty base, deployments are going to happen; however, the vast majority of soldiers living in off post housing receive their housing allowance due to being married or with dependents, most of which remain in the area and paying rent while the service member is deployed. 

You can screen-cap them from your phone with the date and time.

Cap rate does not apply to a 4 unit, it is only applicable to 5 units and greater.
