With substantial equity in your Fort Worth rental, a cash-out refinance could free up funds to purchase additional properties.

This may kill your cash flow due to high interests rates though. 2.

Most of our clients are cash buyers.

The best I've seen for STRs is 80LTV on purchase and 75LTV on cash outs. 

Just purchased recently a small condo cash.

Are you looking to buy more properties in LR or just improve the cash flow of your current one?

There is almost no scenario where a condo would ever positive cash flow while servicing debt, and very little positive cash flow with no debt.If your budget only allows for a condo, find a better place to put your money to work.   

The operating LLC doesn't own any asset, just liquid cash that is rental income from tenant and expenses against rental properties.

Quote from @Duarte Marques: Hey BP community, I'm new to real estate investing and have been studying (reading books, watching webinars, constructing excel cash flow models,...) close to a year.

. $300sqft to build at least.If you have any sort of mortgage on the property you will need an attorney to handle the mountain of paperwork the bank will give you for a lien release. 10k+, also probably some nightmare terms to have to build and sell immediately and god knows what.At this point a year has passed and you have spent at least $60,000 cash, you're about to break ground on a structure that will cost you at the very least $400,000 to build, you are still 1 year away from cashing out because you have to now build a house.
