I had financial issues back in 06-08 (when the nation in general also did). I had debt I couldn't pay, and I had to sell our house short.
I since then have not purchased anything I couldn't pay cash for. However, since then, I have built a business where I purchase about $400,000 a year in products. I have always just used my debit card. Clients pay, and then I buy after I have received payment.
This does nothing for building back my credit. It has been about 7 years most of the bad will be falling off.
I spend 20-50k+ a month for my business. I could be earning rewards on all that spending, and I may need a credit line for business spending in the future. All I could qualify for was a card with $2,000 available balance. I was declined by others. So with this card should I spend $2,000 today, then immediately pay online and do the same every few days, so they see how much I spend and never keep balance on card? Or just use the $2,000 once a month and pay off the bill when it comes?
