Common questions

What are my options in Sullivan's Island 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 Sullivan's Island is the same as anywhere in South Carolina.
What loan size can I expect in Sullivan's Island?
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 Sullivan's Island?
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 Sullivan's Island 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.
