Credit score questions

[Julie Myers]

Hi, first post here. I'm going to do a cash out refinance on a commercial building that I own outright in order to purchase a rental or three. So mortgage number 1 (cash out refinance) will occur this year, then possibly 2 or 3 more mortgages in early 2022. How important is it to get all these done within 45 days so as not to negatively effect my credit score? Has anyone done this over a longer time frame and had negative results? Trying to not screw up here, thanks for any advice.
