That's why it's so unusual that the place is still vacant.

Send out an unusual size. 

It means nothing.Pay $5,000 to "Open the Door" and you have bought a black box of whatever the seller wants to provide (a paper application handed to you from a lender, a website address, etc...)When buying something like this and "Sales Fluff" is introduced into the conversation (vs. hard facts such as, a line of credit will be set up for $X 90 days after doing Y with Z lender, etc...) there is unusually a reason for the "Sales fluff".Ask for a copy of the contract and take the time to read it to see what you would actually get for your $5,000, and if the contract has "Sales fluff" in it--Buyer Beware.If there is no contract, or they balk at giving you an opportunity to read it (pressure you into signing now), it might not be such a good deal for you.And Sales fluff may be a red flag about other parts of the "Opportunity" also.Good Luck! 

Won't they ask questions if they see an unusually large deposit from someone?

Until March, it was not unusual to see offers OVER list price.

Unless you've got something unusual <$500.I'd be looking for stuff like:1) Major CapEx - Life of roofs and siding and paving and plumbing2) Moisture invasion ANYWHERE since this gets more expensive the longer you wait3) Making sure stuff (like remodels and wiring) is up to code. 

Hyper local as said, but it would be highly unusual not to be able to rent the whole house and pretty common only to allow the ADU rental when owner occupied.

@Byron Kim This is certainly an unusual situation so there is certainly not a one right way to handle the situation. 

I have stated perhaps hundreds of times in these forums that this city is unusual, not what most people expect, broken up by geography and history to a greater degree than many others.

I dont know if this answers the original question, since it isn't really a decor style.... but if I was an investor in the "micro apartment" developments being built in various cities including my own, I would worry.With the whole "social distancing" thing, I think it is now much less appealing to live in a shoebox stacked up among tons of other shoeboxes, when the natural density of the area makes that unnecessary and somewhat unusual.
