Should I get a credit card to improve my credit?

I was thinking I could pay it via debit card on the 30th if it doesn’t go through on time.

If I made that much cash I'd knock my debt out in <2 years, educate myself on the local market, open a credit card/build more credit (610 isn't bad anyways) and be ready when you find a good deal.

I like to keep business cards for my attorney.

Fast forward 2 years and we are just getting to the stretch of finishing the house now we are debating whether to RENT it out or SELL it to try to purchase 2 properties or a duplex and use credit cards to fund the partial rehabs.

Our credit/debit card scenario comes with a 3% added charge.In conversations with other companies we are starting to believe that a platform switch may be needed.

I once sold a property to a guy who had an green card. 

From what the loan officer told me, it would be a revolving line of credit much like a credit card.

They lose 10% of their readers every extra second their load.

I don't have the 20% to put down at the exact moment, I have about $4500 in a line of credit, and 10k on a credit card(absolutely do not want to go that route).
