Hi @Marvin Scott Butler! Good for you on your Z-Hills house hack!
There are a couple of different ways to either speed up your savings rate or make it easier to go into the next house hack purchase, but one way is to utilize low money down loans like FHA, which allows you to get into a MFH (up to 4 units, I believe) with just a 3.5% down payment. The more units, the more rental income to offset your mortgage which leads to more money back in your pocket!
Another potential way to increase savings while house hacking is to rent out your extra room(s) to short-term tenants through services like AirBnB and Vrbo. Depending on the amenities you offer, the location, and occupancy rate (among other things), you could really bring in a decent amount of money each month. Maybe even live for free! Something to note, though, is that some municipalities have restrictions on short-term rentals. So I would look into that before doing it.
Hope this was helpful!
Good luck!
