Quote from @Donald Korman: It depends on state laws and local codes. 

@Rachel H.Yes these are 40 year old MH but originally the county said as long as they were brought up to code we would fall under the grandfather status for shared septic.

Would like to connect with PM’s in the 32501 zip code to help me find and screen tenants. 

for a 4 bedroom ,1 bathroom  ,1500 sqf house in zip-code 21216

Or maybe they want a house with a 90210 zip code because that raises their self-esteem.

Newer houses are up to code, but can be more expensive than an older house.

Because this is unpermitted, and he was shut down there is apparently some from of code enforcement case that was opened.

See your local building codes.

Hi John, if the seller's title company is the most reputable in the area and you have an open line of communication with them, when the listing agent, seller's lawyer, and title company have told me there are no liens it's clear, and I can give the title company the liens exceptions list from auction.com "Most liens are removed after a foreclosure property sale, but certain liens may remain.Here are some examples:Any lien recorded on title prior in time to the foreclosing mortgage.First Mortgage (if the foreclosing mortgage is a second or third mortgage)HOA or COA assessment liens (in certain states)Mechanic’s Liens (in some states)Government liens such as state and federal tax liens, city or county liens, US Government liens.IRS liens (IRS may buy the property within 120 days after sale at the price paid at foreclosure sale)Code Enforcement Liens, Environmental Liens, and Utility LiensChild Support Liens"to make sure the title insurance would have coverage for these exceptions, the list from auctions.com, would it still very worrisome to use their title company?

Tax lien, code violation, divorce, probate, driving for dollars, deceased : these are all generally high quality.
