Are older 1950s homes worth it even with the high insurance

[Reva Gaster]

I am looking at an older home to invest in to essentially turn into a MTR. I am just nervous about the home insurance as I have been hearing the home insurance on older Florida homes are between 3k-7k a year, specifically in the Panama City area. With the higher interest rates and high insurance rates, I feel like it can put me in the negative each month.
