The buyer and seller would prepare the purchase agreement, and sometime be able to convince the title company to play along, in a.

You should also get Estoppel agreements.  

I live in this multi-family so I take care of the grass/lawn, snow removal in the winter, etc - however, I plan on moving out this year so I'm in the middle of deciding whether to hire someone to take care of the outside work or include it into the lease for the tenants.For the lease agreement, I used the old one the previous owners had and made small changes but there's nothing specific to snow removal, lawn care, or other general household maintenance (changing light bulbs, air filters, etc.) 

We do not have any agreement between us.

I have a verbal offer deal and need a purchase agreement written up, and a title company to help with the closing. 

@David Duron The business agreement between partners, is a legally binding contract.

If there was a will, the executor or the power of attorney can just write up a purchase and sale agreement to sell it to you.

Things like that should be built into any agreement you have regarding this.Good Luck!

HML said an alternative is to change operating agreement to show >80% equity by primary borrower.To me, running credit on all the partners is the obvious solution before changing the operating agreement.

Utility companies normally let tenants get pretty far behind before the landlord is notified- if the utility company puts a lien on the property for unpaid bills, it is better to have closer control over the bills- If there is a water leak or other problem with the property, the tenant doesn't have to bear the costDisadvantages of having utilties in owner names:- If tenants start using a lot more water/power, it is more difficult to quickly adjust rent or get them to conserve- with pandemic or other freezes on rent or evictions, there is no recourse for utility increases- if the tenant qualifies for low income utility pricing, it has to be in their nameOnce you decide what your guiding principle is, you can align your current rental agreement to match.
