First time buying multi-family. Looking for options

[Hunter Van Wyhe]

I Own a single family home and have been house hacking for 2 years. I would like to get into some quadplexs that are for sale in my area. Here is the situation. A seller is selling multiple properties. I can afford one but would need to refi my single family. Another idea I have is trying to aquire all properties and do a bundled deal but would need help financing. Any ideas would be appreciated!
