I'll save you the details but...Per door cost: $63,300All in Cost: 700kTotal Revenue: 137k(ish) annuallyNOI: 65-73% (in the expenses we included: insurance, taxes, $75/month per door repair expense, management fee 8%, grass cutting, & a misc fund for random crap business license, etc.)Now...

You can start to educate yourself on the individual components; how much does it cost to paint on a per sqft basis or what is an average kitchen remodel.  

One of the SF (which if I go this route will be my starter home) is at the heart of my city within a 10 minute drive from almost EVERYTHING while the second is a bit on the outskirts and near all of our oil and gas company's (hundreds as per google).  

I liked the tenant, school is starting back etc, I told them they could pay first month and security deposit and I would let them have the rest of August for free.

@TJ Dittmar What would something like that rent for per month, $1,800?

You have to pay depreciation recapture and gains on the pro-rated time it was a rental.

-PITI minus (rents x number of bedrooms) = your debt obligationIf what you owe at the end of the day is less than what you would spend on housing per month, that's a win! 

Billing is different for most and more than likely, you'll pay a retainer of some sort up front and have a balance due. 

Rent is by the month not per day.

In the next 5-10 years, I plan to leave my current industry and transition to real estate full-time, so I’m especially interested in how this could impact that goal.Current FinancialsRoth 401(k) Balance: $105KContributions: $79KEarnings: $23.5KSalary: $109KContributing 6% annually ($545/month), with a 100% match for the first 3%Investment Growth Assumption: 8% per yearCurrent Rental Cash Flow (Pure Profit After All Expenses): $7,500/month (9 units)Potential New Property Cash Flow (Pure Profit After All Expenses): $1,300/monthCurrent Real Estate Portfolio Value: $1.4MAfter New Property: $1.7MWithdrawal Breakdown ($60K)Tax-Free Contributions: $45KTaxed Earnings: $13.4KWhy Only $13.4K Is Taxed and PenalizedMy Roth 401(k) balance is made up of:Total Balance: $105KContributions: $79K (75.24% of total)Earnings: $23.5K (22.38% of total)When withdrawing, the money comes out proportionally from contributions and earnings.
