It is the principle of the thing.? 

I have, hence, excluded CAPEX from my calculations with a principle that I would only analyze houses that are no older than 15 years and the big ticket repair items have been recently replaced by the owner- I know its a long stretch, but, was just shuffling around my numbers to see what makes sense.

@Adam Pervez estimating semi fixed expenses is easy, you can easily pull tax amounts, get estimates for insurance, you should know what your monthly principle and interest should be etc...Most newer investors get into trouble estimating the variable costs of CapEx and maintenance. 

Not to mention - from that company that you already engaged.So either a) follow the KISS principle b) accept the complexity and the need for one-on-one quality help or c) play the Russian roulette and take your chances that things will work out fine on their own

Your CPA would definitely be the best to know exactly, but here's a nutshell: $320/month cash flow For ease I'll say $180/month average paid to principle means $500 before other expenses. 

Members should do their own due diligence and have a deep understanding of investing principles before just blindly accepting what a stranger online has to say. 

At that point, I would be completely maximizing the cash-flow on that property which I would use to make extra principle payments on the next property to help pay off that property as fast as possible.

You are paying your investors principle back plus interest back.  

I would personally use 1-2% to remain conservative.The projected year 1 returns are as follows: (1) Pre-tax Cashflow (Also known as Cash on cash) $1,817 (3.42%), (2) After-tax Cashflow $1,997 (3.77%), After-tax + Principle Pay down $5,980 (11.28%), Total Return (After-tax + Principle Pay down + Appreciation-3%) $13,930 (26.28%). 

Other might be deductible if you have other rentals.3) If the sale falls under the installment sale, the portion of the payment can be written off as business interest expense. the payment of the principle is not deductible.
