If you have a credit card or car payment, use that cash flow and knock it out quickly.

You definitely don't want to over-leverage and end up with a house of cards that'll fall over with a gust of wind.

This is broad question but here's a couple pieces of advice:1) Put it out there what you're looking for (i.e. facebook/insta/Snapchat/craigslist posts), car magnets, business cards, etc.);2) Secure funding ahead of time (or at least know your funding strategies);3) Have a good home inspector on your team (he/she may be the difference between negative cashflow and positive cashflow);4) set up automatic cragislist email notifications on potential deals (set up key words);5) buy properties in areas that you wouldn't mind your own family living in; 6) Remove emotion when sifting through deals;7) Don't give up

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!
