How to get multiple refi quotes at once?

[Shawn Wainsely]

I have a rental property at 4.75% as an investment property, obviously rates are much much lower now. 

I have been calling around and can't even get calls back or get a hold of mortgage departments because of how hot the market is. I got a refi quote from my current provider at 3.25%, problem is, they were giving me a lot of push back and did not want to approve me claiming high debt to income ratio. My debt to income is 10% with only one liability which is the mortgage. Point being, they were giving me a hard time and not wanting to approve me despite already approving me when I bought the property.

Is there a platform where I can get multiple quotes and get through this process? I know there is quicken but I never had a good experience with those sites, aside from getting a lot of scam calls and emails.
