@Coty Dolan I think your vacancy is too low.  8% is one month. 

Some landlords are now offering reduced rents just to fill vacancies during COVID-19.I would appreciate your thoughts on if we should politely respond the rent will be the same rate for the new lease.

Also, don't forget a vacancy factor!

That’s to take into account vacancies and misc repair.

Too many people are allergic and will increase our vacancy risk. 

If it was me I would increase the vacancy and repairs percentages to be safe.

When deciding on using financing or cash I would think about what happens if you have a high vacancy? 

That would be a true BRRRR.As far as the analysis:I'd bump up the Vacancy a bit.

Vacancy of 5% is your tenants staying an average of 20 months I use 8%.

This means that your rent collections will be sufficient to pay your entire mortgage payment and allow you to live mortgage free, unless and until the renters don't pay or there is vacancy.
