If you have a VA mortgage you may get 100% refinance, without income verification or an appraisal
You would need to prove the ability to repay the refinance mortgage payment thus, having the correct debt ratio. You would need to be employed in the same career field for a minimum of 2 years. You must agree to stay in the house for a minimum of 2 years.
To find out the other necessary documentation and information needed to qualify for your refinance.
I hope this has been of some benefit to you, good luck.
"FIGHT ON"
Typically all the same requirements as for a purchase transaction. A refinance can generally close much faster than a purchase because there is some reduction in the paperwork and you are not dealing with a seller, inspections, etc. But you still have to have good credit, adequate income, and the property has to be worth enough to support the loan.
The same things to qualify as you needed for he initial mortgage
same basic things that were considered in the original loan, your equity, you loan value, you employment, your credit score, etc. etc. etc.
