For commercial spaces - I prioritize a long term / cheaper tenant over a high rent with the potential for vacancy. 

I also have credit cards that I can turn into cash, but the interest rate is an issue.I just don't know what the right move is to get that cash and keep that rate.Am I missing any other strategies or ways I can gain that capital at a cheaper rate? 

The goal is to try and do 2-3 of these projects/year. margins are too low. you need to work on finding land cheaper. look at 500 pieces of land and underwrite them and the exit. we did that for the last 8 months while we have broken ground on a few deals and we focus on where can I exit at the highest which tends to be urban core infill lots. we do this in Columbus Ohio and expanding to where I moved in miami soon. the margin you have is too low though for new construction. how many new builds do you have? 

It's getting cheaper and easier!

If it is cheaper to own, you may want to buy and even if you sell in 2 years (assuming the development is finished on time), you may still come out ahead in terms of selling the property vs paying someone else's mortgage.

A few houses (cheaper ones) were bought in cash and were never mortgaged.

So which PM is cheaper?

And on the other side you have folks who have done the math and understand the time value of money and have quickly realized that your money is better allocated into an actual real estate investment and purchasing a much cheaper term policy on the side.WL policies are absolute crap for RE investors who have much better avenues in which to invest their money. 

The solution I outlined above is a cheaper, faster and more likely to result in achieving the outcome sought by OP. 

Leaning towards 30 year loan since 10 year only 0.25% cheaper.
