Seller wants to leaseback one year or more on sale of house.  Because of Covid-19, there are no late fees and no evictions in my state currently, regardless of rent received or not.   So it it reasonable to ask that 1 year's rent + security deposit be put in escrow from sale of a house?   What might an escrow company charge in fees to handle this?

I could reduce this requirement if they have excellent credit score (i.e. 760 or higher), but I have reasons to believe that isn't going to be the case here.   Either way I will require at least 630 score as I normally do anyhow. 

I might phone the title company I am working with Monday morning... that will probably be easiest to find out the cost.
