You can have more than one credit card, of course if you cant handle loans well then I wouldnt recommend this.

Just my view.Your ace card is once you get the title, you threaten to move the home.  

I am considering a deal in my market in which I found a significantly underpriced parcel of land blocks for major transportation hub in a gentrifying area. 

They basically didnt charge over x amount of a credit card and waited until the bill came in so they know the purchases hit their report, and then paid the bill in full each month.  

I only have $60k in available credit through my credit cards, and my real estate agent won't accept them anyway -- so that's out.

If you really really want to buy an apartment in New York City the first thing you should do is to go to a Mortgage originator and go to FTC.gov and download your free credit report and bring that with youYour past credit history is not the biggest problem; what is the biggest problem is that you are aggressive in building new referencesThe fastest way to build a stronger credit report is to do what's called "bank round robin"Take $1000 and go to bank one like Bank of New York, and talk to the manager and say that youd like to build a credit rating and get a mortgage within 12 monthsTheyll give you a secured loan with your thousand; then you take that thousand and go to bank to like Wells FargoTell the bank manager the same thing, that you want to pledge that thousand as a secured CD or savings account and get a  $1000 loanThese are called installment loans and now your job is to double up on payments on both loansSo it say your payments $80 a month with each loan or 160 for both of them every monthYou then make four payments every month and they'll be paid off in six monthsAt the end of six months you have 2 open accounts with two banks on installment loans, and paid as agreed with zero balancesYou may want to take one of those credit cards and establish credit at Macy's or other department stores with no more than two of them; Buy something and pay it off right away or keep a small balance because credit utilization rate is an important factor; this means keeping a 30 to 40% balance and even though it cost interest get you more points on your FICO scoreYour length of job in the same industry, you length of residency in the same place, and how you pay your bills on time will build a credit rating faster than anythingFYI I do lease-option assignments where I help the tenant buyers get mortgagesThis plan works faster than anythingGood luck

And if you play your cards right, you could acquire 8+ doors even with the limitations.I completely disagree with Justin.

Heck, even leave business cards after you eat out for dinner (I do it every time!). 

Last year I was able to buy our current home with cash for 35k and I put 20k on my credit cards plus 5k out of pocket to fix it up myself.

Leave your credit cards at home (except enough to buy dinner and entrance fee).
