Mortgage Help for Self-Employed

[Christina A.]

Hi members and mortgage pros

I've been self employed for a year. Can prove consistent income around $8k/ month. Credit is 800. 

I'm sitting on 500K cash from a recent property sale and have 1.5M in investments. Last, I own a vacation rental that's been cash-flowing 30K/ yr for the past 2.5 yrs. 

Looking to by my primary residence in West Palm Beach, FL.  Spend approx $500K. 

So far I've received rates of 7-8% on a 30-year fixed with 20% down. Having a hard time swallowing this. 

Prices just keep going up down here. It's nuts. Can anyone offer a better rate? Or any more creative financing suggestions? 

Thanks in advance!
