For example, I manage an apartment building on St Pete Beach Florida, a block or so from the beach, surrounded by hotels and vacation rentals, but the zoning for that particular parcel only allows for a 30-day minimum rental. 

You should treat all expenses seriously, but be particularly cautious in your record keeping for these.If you're using rental management software, many of them allow you to upload copies of receipts when creating an expense, which makes record keeping really quite easy.

How are people staying productive at this time, particularly in terms of acquisitions? 

@Eric KrikkeIn no particular order...1.

If you zoom in on property B, there is a way you could consider yourself 100 percent leveraged on that particular property but zoom out.

In this situation, I would speak with multiple banks unless there is a reason why you would want to refinance with this particular bank.

So for these particular cost segs, they were on commercial multifamily properties, but you could absolutely do a cost seg on a SFR and a turnkey one even.

Are there particular lenders that are more advantageous than others?

There are many duplexes & triplexes in the city (even one's built years ago), that are not zoned for their particular use.

I don't want to give them a specific reason why, I just want to say something like "sorry, we have chosen a different tenant".BUT...if the house stays on the market after that, it's going to be obvious that I don't really have another tenant, I just don't want that particular one.
