Ever had any hiccups from credit inquires? my HELOC was denied..

[Jordan Thompson]

Hi everyone!  I am (have been) gearing up for my first deal for about 4 months now and after I refinanced the primary mortgage, I got my pre-approval letter from the same lender and went to open a heloc with a credit union.  I got denied for too many inquiries.  Here's the basic overview of my personal finances:

1. Credit score at refinance 3 months ago was 760 and still in the 720's

2. I owe ~182k on the primary home.

3. No auto loans, student loans, or credit card debt; I only owe the mortgage

4. Wife can't work (medical) so that lowers the income

I got a denial letter due to 5 inquires on my report; 1 of which was THEIR inquiry to my credit.  1 was the refinance that I did, another was a small credit card at the beginning of this year to build credit (my CU didn't report to agencies at the time), 1 from the denied application to the same credit card company 4 months prior for a higher level card, and 2 others from about a year ago, but these were within a week of each other.

Here's my question: as some of you more seasoned investors are closing multiple deals per month, quarter, and year, you certainly have more inquiries on your reports; have you ever run into a hiccup with this?

Thanks in advance!
