If you have 1-2 properties it certainly seems unpredictable.And... the spreadsheet math of 'I will consistently net $227 a month, and exactly $227 a month, from this property, starting in month 1 and then going forever' was never correct.

Draw schedule to be agreed upon prior to closing.Term: 1 YearFee to Lender: 2.5 points – ($13,125 paid at closing from loan proceeds).Interest Rate: 11.5% Interest-Only billed monthly on outstanding balance.Interest Reserve: $15,000 – approximately 6 months interest, paid at closing from loan proceeds.Once interest reserves are depleted, borrower to make interest-only payments monthly.Pre-Payment Penalty: Should loan be paid off prior to interest reserve funds being depleted, a pre-payment penalty will be charged equal to the amount remaining in interest reserves at time of payoff.Loan 2: Loan amount 490,530.60Lender Points: 3%broker points: 1%rate: 11.99%Term: 12 months (interest only)Prepayment penalty: NoneProcessing fee needs to be wired before LOI can be issued these are just math questions.. 

-Taxes-Home insurance-Mortgage Insurance -Maintenance/Repairs-Capex-Vacancy-Property Management (many include this even if you don't plan on initially offloading to PM)-Utilities Let's say all in expenses are $2,000 per month for easy math purposes. 

You definitely need to do homework on local restrictions.   

At least 25 to 30 people signed up…you do the math.  

Check your math to make sure you're not violating this or your contract could be voided.

Meaning people don't want to move out of their home either, so the supply is also lower.Do your homework on what sort of house you need, what area, etc. and buy what works for you.

Do the math and see what you'd save if you put 20% down (ie mortgage insurance) and if you put 10% down; and what your payments would look like. 

So, let’s just estimate and do the math $600k potential as Kris keeps spewing -$175 from the one deal her team messed up we are at $425 - $200k roughly I’ve decreased sales prices we are at $225k - about $150 estimate in dead deals she included (just estimating I didn’t go confirm this) we are at $75k - $50k in mailers, subscriptions etc we are at $25k -$30k I paid for her course I’m NEGATIVE $5,000 STILL and that doesn’t include her “50/50 split”. 

I know you were looking for mathematical formulas, but for me this Overrides any math.
