What would you do with 150k in equity?

[Crystal Wilson]

Trying to get the most out of all my equity I've gained. I currently own 3 long term rentals. I'm planning on getting a 2 unit to live in and airbnb. But I feel I could go big and get a big multi family. Wondering if I could get a 3-5% down loan? Already got approved for a 20% down and in proses of refinancing all properties. Just need some advice or ideas from other investors. Thank you!!
