Better check with yours first.Generally pose no threat as long as they are not disturbed.

@Greg Farabaugh were you able to see the property before making an offer or did they say they'd only do showings with an accepted offer because they didn't want to disturb the tenants?  

Google voice them with "Do not disturb" enabled.

It is, however, inaccurate and, more disturbingly, incomplete.The tax benefits of business entities are not TAX AVOIDANCE, they are tax liability reduction.

Assuming you aren't disturbing the commercial tenants' businesses, I don't see a reason why they would leave. 

A lot of times the local jurisdictions (at least here in WA state) have a lot of storm water requirements that kick in after a certain amount of square feet of the site is disturbed with new impervious surface...so thats where civil gets involved regardless of the complexity of the site bc thats state law.I stand corrected.

If you are not disturbing then you don't have to remove it. 

In my initial offer, I requested to allow me to survey current tenants but seller denied under pretext not to disturb tenants.

A few things I've seen:no rentals under 1 yearowner is responsible for any "disturbances" so if the tenants are loud, etc.. the condo assoc could fine youIn general I'd be more inclined to look for young professionals than college kids as mentioned though if its the only possibility get a lot of $$ up front and make the parents co-sign.

in affected areas first.Taking out drywall is also fairly easy (big hammer, regular hammer, and flat prybar is about all you need) but is very messy so enclose the work area, wear protection and ventilate it.Note if if this is a pre 1978 house which it looks like it is,   and you plan to rent it,  then legally speaking you must be lead paint certified and follow abatement procedures when removing or disturbing more than six square feet of painted surface in any room.
