If my math is right, and if we assume a cap rate of 7%, that means this property has a net operating income of $565,000 (the list price) * 7% / 12 months / 16 units = $205.99 per unit. 

Then pay full amount at the end of the term (ex 30 yrs depending on loan terms) With that being said 70% LTV with 6%& 30% with 9%. 15% intrest (just using simple math) i would pay monthly along with expenses i could still generate a very positive caah flow.

This is a coin opp laundry room and after doing the math , I dont think was even breaking even after water/electric . 

Same math, 4.25%+.64%= 4.89% effective temporary interest rate, dropping to 4.25% once the mortgage insurance drops off. 

If I did my math right, which maybe I did not this seems to be preferrable...Borrow 55k out of my home for about 350 a month extraNew loan about 1400Rental income about 1900Which should leave me about $500 cash flow.200 for rental agency and 300 a month into a fund for repairs until that gets reasonably high and I can start taking profit.Am I missing something?

I am a high school math and computer science teacher and got my real estate license a while back and just recently got it reinstated.  

. - $200Utilities - $400Total Monthly Spend: $8400Now I didn't plan the math this way but it worked out to be exactly about what a 200k earner would bring home, post tax, each month - which effectively means this theoretical person is living paycheck to paycheck. 

If so, it becomes about math at that point.

A higher appreciation area will always have better actual cash flow given enough time than the lower appreciating area (simple math). 

Also there isn't going to be a trade secret in your math if you are looking at rental properties that a realtor could steal, same with flips, but flips are more unique every time.
