How do I get funds without tanking my 750+ credit score?

On the refinance you do not pay points if you use a FDIC bank or credit union so you avoid the BS fee's.

It's ALL required to go from "BAD" to "NOT BAD", then from "NOT BAD" to "OK", then from "OK" to GOOD, then GREAT.

Really analyze the deals you look at and, if your modeling says it's a bad deal, don't get emotional and do it.

Or is a home equity line of credit still the popular method?

Prospective residents could be required to answer customized landlord questions while also needing to provide a valid credit card prior to entry.

Some allow a member that holds at least 25% of the entity to be a guarantor and they will be the only one with their credit pulled, while other want majority ownership to guarantee the loan, so in that case it would be both of you.

My credit score is really good and I have around $450000 mortgage  on 2.75  rate for 18 more years.Thank youN.

You typically need 20% for the down payment and there are some credit score requirements as well. 

DSCR loans are based off of down payment, credit score and either actual or market rents so it helps to supercharge an investor's real estate goals and net worth.
