Landlords - legals fees, fines and penalties due to non compliance, and costs to arrive at compliancy.2.

New tenants quickly learn non compliance will result in them being unhappy and having to move. 

@Cody L.Per my attorney I’m in compliance with dodd Frank so long as I don’t do more than 3 in 12 months.

I bet there would have been even less initial compliance with a “you’ll be home for 2-4 months” mandate.

(c) If the court determines that the tenant’s inability to stay current on the rent is the result of increased costs in household necessities or decreased household earnings due to the COVID-19 virus and the court finds that it would not be an material economic hardship to the plaintiff and if the court determines that no cause exists after review of a timely response from the plaintiff, then the court shall make the following order:(1) The tenant shall remain in possession.(2) The rent for the rental property at issue shall be reduced by 25 percent for the next 12-month period.(3) The tenant shall make monthly payments to the landlord beginning in the next calendar month, in strict compliance with all of the following terms:(A) The payment shall be in the amount of the monthly rent as adjusted pursuant to paragraph (2), plus 10 percent of the unpaid rent owing at the time of the order, excluding late fees, court costs, attorneys fees, and any other charge other than rent.

Thanks to my 100% passive (ok, fine, 95% passive income) strategy of investing in Private Loans using my own money to fund other investor's RE Investing, I have been able to quit my job of 8+ years in Healthcare Compliance Consulting, and traveled to 9 countries with my family of 4 last year!

I would also advise that there will be ongoing, routine inspections of the common areas to ensure compliance.  

If you can't get that fancy, at least use DocuSign or similar to get digital signatures, and if you are in Maine, don't forget all the compliance docs: Radon, EFF, Lead, Bangor Tenant Rights (I see you live there). 

Everything from tenant screening, lease drafting, rent collection, compliance issues, insurance, evictions, rehabbing, etc.

All homes need to be updated with a new CO upon sale to get a mortgage  or cash with a permit to bring into compliance.
