Common questions

What are my options in Boulder if my credit is poor?
Borrowing is still possible, but expect a higher APR and a smaller approved amount. Lenders that accept lower scores hold statewide licences, so what is open to you in Boulder is the same as anywhere in Colorado.
What loan size can I expect in Boulder?
Most personal loans sit somewhere between $1,000 and $50,000, though the figure you are approved for turns on the lender, your income and your credit. Model the monthly payment first with our personal loan calculator.
Do I have to pledge anything to borrow in Boulder?
For an unsecured personal loan, no — there is nothing to pledge. A secured loan, such as home equity or one secured by a vehicle, does require collateral, and default puts that asset at risk.
Does comparing loans in Boulder cost me credit score points?
Not during pre-qualification, which normally uses a soft pull and leaves your score alone. Submitting a full application triggers a hard inquiry, which can trim a few points briefly.
