So thepointsguy calculator would suggest that you still use the credit card at 2.5%.  

But don't take my word for it; do the calculations for yourself;4.

The rent is calculated from the zillow estimates.

To calculate the cash-on-cash (CoC) return for the rehabbed unit, take the annual rental income from the newly rentable unit and divide it by the capital invested in the renovation.Formula:CoC Return = (Annual Rental Income) / (Rehab Cost)This will show you the return based solely on the funds you put into the rehab.

BP calculator does it, its an estimate but works8. 

You need to be careful and make sure you're not including the credit card/paypal payments when you're calculating the amount to use in the 1099-NEC/MISC.

Also if it is intended to possibly be a rental you should calculate the end result of the acquisition, the debt service, the rehab, etc and pretend to get a loan to refinance. then look at the potential rent to offset that monthly cost and see if it would cash flow.

Are most of you including things like property insurance, etc in your CoC calculations?

I'm using the BRRR calculator to analyze a few opportunities. 

But what I found ironic are:- Andy, who has been working full time in RE for 4 years, are finally going to make $50K passive annual income from rental (with a flawed net profit calculation that didn't income vacancy rate, maintenance fee); and he said after attending the $39,500 program, he paid total $80K--poor Andy didn't even make his initial investment back after four years and yet they are demonstrating him as a success case.- In fact, Andy is now a "trainer"--which seems to me, training is their stream of income, not real estate- Andy revealed that he found his deal leads through words of mouth; what's ironic is the instructor kept on selling the importance of the company's Elite Success Software and told us we can't make deal without itInstead of teaching something, they spent the whole third day (at least until 1 pm when I finally decided to leave) selling the program.
