I'll see if they let me get a credit card.  

That letter should be your ‘get out of jail free’ card if they try to hold back your deposit upon move-out.

Only "credit inquiries," and they are categorized by type of creditor, with mortgages being the least impactful and credit cards being the most.

I gave him my business card.

I currently have 1k in credit card debt on one card, a auto loan under 11k and a atv loan under almost under 2k  My credit score is a 758 and i have only 10k in my savings. 

I do get people occasionally who will ask me about maxing out their credit cards to do a deal or want me to introduce them to someone who will put up all the money on a deal.

Well assuming that you always buy properties that cash flow and that you don't increase your debt that shows up on your credit report (personal home mortgage, car notes, credit cards, etc) I hope that makes sense!

There are advantages to being online (for example, online backups to the cloud, credit card services, bank integtation) but we did not feel that we needed the extra services at this time.

Do you have a credit card?

If they are receptive give them a card and, more importantly, get their info so you can follow up.
