Hardwired and interconnected vs. solely battery operated depends on what municipality or police jurisdiction the property is in, the date of the requirements, the grandfathering rules, and the last time a permit was pulled, which would have probably eliminated grandfathering.

They're trying to eliminate a landlord's ability to ask for market rent if a tenant moves out and you have to rent to a brand new tenant that you've never rented to before.

You eliminated your listing from every buyer’s email that told their realtor they wanted to spend $1M or less. 

This should eliminate the homeowner (1) selling a property while remaining liable for the note (subject to), (2) tying  up his property with a “buyer” who has no intent to close unless he finds someone to pay a higher price (wholesaler), (3) paying above market rental for an option to buy that can never be exercised (4) purchasing a property from a fix n flipper who did shoddy rehab, (5) purchasing a property with nebulous legal title, (6) contracting for home improvement with a fly by night contractor who then puts a mechanics lien on the property and (7) “listing” with a wholesaler disguised as a Realtor who doesn’t put the home on MLS. 

ACH payments by their nature take a few days to know if it actually clears (you can know faster for credit card payments). 7-10 days I'm guessing is something like this:2-3 business days Tenant -> Zillow2-3 business days Zillow -> LandlordSo in summary, you'd almost surely know within a couple days if the tenant sends a bogus payment, even if you don't get it into your bank account until later.

@Alex Todd, yep, you would qualify for both as long as you sell next year in time.So then the question comes down to - If you're going to make the same amount of money either way would you prefer to sell now and 1031 (but eliminate the risk of another year holding). 

When 62 percent of property owners have been eliminated from the world of real estate transactions, that just leaves 38 percent to play with. 

See if you can make the entire unit electric so that you can eliminate the gas problem. 

From there you'll be able to start eliminating what does and doesn't work for you and that will help to shape your buy box. 

I'm hoping that is not case.I would add this to the lease about starter supplies including cleaning products.This will eliminate any question in the future.
