Send me a DM and I can send you a link for the All In One mortgage savings calculator.  

Here's the breakdown of rental income and expense analysis:1.Annual Gross Income: $25,800 (Monthly rent of $2,150 x 12)2.Annual Expenses: $25,800 * 0.40 = $10,3203.Annual NOI: $25,800 - $10,320 = $15,4804.Annual Debt Service: $10,680 (Calculated previously using a mortgage calculator with a loan of $131,775, 7.25% interest, and a 30-year term)5.DSCR: $15,480 / $10,680 = 1.45 (approximately)

Focus on one or two target markets, get familiar with the numbers, and use tools like BP calculators to analyze potential properties.Whether you start now or after graduation depends on your bandwidth, just have the right systems and support in place first.

Here's a bit more in detail about how rates are calculated for DSCR loans:1.

Rough calculations on what I need to be looking for:90k deal (purchase and renovations to get max rent)20% down = 18k from me80% bank loan at 8%, 20 yr amortization = 72k-------------------------------------------------- Here's my DSCR calculation:Calculate Net Operating Income (NOI):Monthly rent: $125040% expense ratio (taxes, insurance, repairs, vacancy) = $480NOI: $1250 - $500 = $750Calculate Monthly Mortgage Payment:Loan Amount: $75,000Interest Rate: 8% per year (0.08/12 = 0.006667 monthly)Loan Term: 20 years (20 * 12 = 240 months)Monthly Payment ≈ $627.83Calculate DSCR:DSCR = NOI / Monthly Mortgage PaymentDSCR = $750 / $627.83DSCR ≈ 1.20Therefore, with a $75,000 mortgage at 8% interest over 20 years, the DSCR is approximately 1.20

Id definitely allot yourself an extra couple weeks though for your calculations.

Interest only loans allows them to get a goal profit of $500-$600 per month per property.3) Each acquisition would require 20-25% down at an 80-100K purchase price. 4) Closing costs, and the Eric Spofford turn-key transaction fee of 10K would be in addition to the down payment and were not included for the purposes of calculating the cash-on-cash return.

Don't worry about any of his "calculations" or "reasons", in my experience judges have no time for that stuff.

When you looked at the numbers on the top 3, they all had good cash flow and great appreciation (the numbers were calculated as though no equity had been extracted). 

BiggerPockets also has a calculator to analyze deals, and I highly recommend you start this as soon as possible, even if you are not ready to buy.
