No debt and good credit score.Are there any steps I should take before I contact one?

If credit is strong and equity is high in the property you may be able to restructure that loan into a traditional conventional mortgage.   

If you cannot refinance it is unlikely you'll be granted the novation and it will take a lot longer to get an answer on that.The beneficiary of that assumption has to fully credit qualify so, while yes, I agree that might be an option, it's not a given.

@Brent BagenStessa is also a good option that is free with BP Pro. 

I have a credit score of 765, with a good amount of savings. 

I cannot recommend much about the areas in Dallas, but i can definitely offer my expertise as Mortgage Loan Officer, Investor and Short Term Rental host.Feel free to reach out :)

One strategy I've used is offer a higher price and ask for closing credits to buy down the loan and negotiate once it's in contract for credits on repairs. 

If your credit is strong you may be able to access an equity line for up to 95% combined loan to value. 

We were asked to select at least 6 and put them on a credit card - we would make the money back in no time, so the promise.A few weeks later I got a call asking me why I did not sign up.

Feel free to reach out if you need assistance.
