I have a client exploring a new build (her home recently burned down). 

Mobile homes and such? 

Mobile home parks can provide consistent income, and if you manage it well, they could become a significant source of cash flow.

If you are over leveraged, aren't prepared/don't have a plan to get out, you will get burned easily.

Things like septic pumps burning out, steam room dying, guests catching the grill on fire and leaving burn marks on the hardi siding, emergency bug treatment, above ground pool which is ridiculously hard to manage in our heat & having no time to deal with it if it starts to go, laundry & drying time for all the towels and linens, etc, etc.There are plenty of things we can and will get better at, but I'm prioritizing the stress level of my people as well as the very near disasters we've narrowly avoided, over the little bit of extra revenue we'd generate.

All the rehab deals we had took significantly longer than expected, costed more in rehab, bank refinances did not necessarily go as planned, contractors burned us in various ways, property mngt was a nightmare, etc.

@Frank Rolfe's Mobile Home Park Bootcamp is the gold standard!

Should I BRRRR a property or pay cash for a couple mobile homes?

Its all mobile through phone, you'd need to be on the host account to view anything, or in the car with them to learn anything.

That might help rent increases as that inventory burns off.
