@Felicia Otoo To determine the best refinancing strategy, consider the following:1.

You are better of funding the fix and flip deals with a HELOC and refinancing with a DSCR loan . 

I'm thinking of starting with buying/rehabbing my first house being cash, then refinancing after I rent it and repeating.

I've got a few contacts in the area who've been keen on investment opportunities like the one you're describing—buying all cash, rehabbing, refinancing, and wrapping.

Have bought, renovated, refinanced and sold rentals in my portfolio.Besides monthly cashflow, you can cashout refi every 5-10 years or when increasing rents support the ability to do so. 

We refinanced and pulled cash out, and they will pay off the debt a second time.  

The warrantability will come up more on the back end when it comes to refinancing or selling and the rehab aspect will impact you more immediately as it may cause you to adjust some of the work that you're looking to do on the property.

Buying a single family below market, living in it then refinancing and renting is a good option.Do the research...do you have the skills to renovate a house?

To your point in number 3 - yes I have done utilities included for the sole purpose of being able to show as much money coming in for refinancing and for the banks.

If you find out what their dreams are, perhaps refinancing can align with those dreams if you position it the right way?
