I bought a portable induction burner from Costco in anticipation of not having gas available in my Honolulu retirement condo.  

Olympic sized pool, hot tubs, on-site restaurant, yoga, pilates, gym, steam, sauna, and management company to take care of it all.

Greetings,This is my first post.When the sale of the power plant I work in is final the old owners will give me my portable pension.

Your other alternative would be a portable dishwasher.

@Dallas Trufyn  I'm not sure these add any value as both the fire pit and grill are fully portable and I'm not sure if anyone would assume they stay with the property upon the tenants vacating.The looming issues here are the failure of these tenants to abide by the lease terms, and the exposure to liability they have just generated for the owners.  

I recommend a portable unit.

If you have a few rentals, then a portable room air conditioner is a good investment for these situations.

I bought him a portable cement mixer for $2,500 to use on my house since he would have to rent for $150 per day. 

Updated kitchen flooring, drain tiled the basement, new appliances, new light fixtures, rebuilt sauna in basement, new carpeting, light landscaping, new roof (insurance claim for hail storm), and lots of personal item cleanout and cleaning.
