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."

Low fixed rate, interest only for the first 10 years, and have check writing capabilities.

@Jobee Vincent Buenaventura well, if most lenders are taking 60 days to write a cash out loan then you would only need 2 more months to start the refinance.  

Things I imagine will be an issue:- City approval as house is currently a legal duplex- City may force me to rent it as a single family home right away- Parking - another car park may be needed to get approval from council but I've heard exceptions can be made- Entire project going over estimate by a lot- Not being able to get financing then having to turn it into a single family home rental which won't cash flow so well.Geez, writing it up like that makes it sound like a terrible idea! 

Write out the questions you have, whether they fall into the details category or even just the “I don’t know where to start” variety.

What I detested was the process: collect all the bills, open the mail, rip off the stub, put the remainder in that bill’s receipt folder, write the check, make the journal entry, stick both stub and check in envelope, put on stamp, lick envelope, write in return address, etc.
