I am looking to find more off market homes in the surrounding Rural Markets of Ft Worth for flipping and/or keeping for rentals 

I could be off here, but my understanding is that if you are already in the business, you have a precedent set and can depreciate furnishings as you scale your portfolio. 

That means you can never take cash out again unless you pay it off.

I did hear on one of the videos I watched to try to purchase off market. 

I would like to know by what process can I get a Special Warranty Title converted to a General Warranty title, if I pay off the liens or second mortgages ?

Property paid off in 20 years.What is more important?

The earlier you start in your RE journey, the better off you will be in the future.

Our niche is sourcing off-market deals for developers we work with that buy them and build new construction on them.

Cash out refinance, pay off the HELOC and then repeat like the BRRR strategy. 

The new mortgage on the new $340k duplex home which is an FHA loan is going to be a monthly payment of $2800 and we will refi ASAP (the current rate is 6.7%) when rates go down.We have done some nice improvements on the SFR and will be refinishing the wood floors before a renter moves in (July 1) so feeling like it's a great opportunity for the right long term renter and we plan to screen prospective tenants well.We are taking a $20k HELOC on the SFR for the downpayment and plan to pay that off within 12-18 months.
