Brokerages get bought. The schools will tell you what is required. Submit those docs as you have them. That’s not a concern
As for home value, follow the instructions. Don’t deviate.
Many schools don’t count home equity and those that do - you don’t want to raise a flag. So follow the directions. After all, two identical homes can have aesthetic differences or renovations and yet the value of those renovations doesn’t move the needle that much. And $150k unless your house is $3 mil - seems very high and if your house is $3 mil, you’re not getting aid
So do as instructed. Let them figure out the rest.
