You can give the money to your sister but have to write and sign a letter stating that it is NOT a loan and a gift.

In underwriting you will likely have to write a small letter to the underwriter explaining the reason for moving so soon.However, if this is going to be an investment property that you do not intend to live in, you'll have to put down anywhere from 15-25% depending on how many units. 

Depending on the laws in your state, the tenants may need to be notified in writing of this information. 

There's probably nothing of value so there's little risk of someone suing you for throwing out junk.As for the unpaid rent, you may have to write it off.

You state you're buying out the other heirs/beneficiaries, but then you write you want to show minimum consideration on the deed. 

Given the current eviction moratoriums in place, is it still within our rights to simply inform that tenant in writing that we will NOT be renewing the lease? 

@Tony Escobedo telling someone you have cash or writing a cash offer, when you don't have the cash is fraud.

As I say that, I say I do highly respect your time taken to write back to me.

Instead of wasting your money you might want to print out the harmful effect of not replacing the filter for residents and make sure the tenants always get a copy and warning,     Also you can take it a step further and you can-write it in the lease that "if the filters are not replaced regularly tenant understand that this will cause a $300 repair bill at the end of tenancy, where tech or HVAC cleaning co. needs to come out and clean the system."
