Septic could be problematic since oils and cleaning chemicals could be discharged and then leach into soils/groundwater. 

I have not gotten plans drawn up yet as the soil test was just done.

@John VanharaIs the building a steel structure underneath the masonry? 

I would definitely be very frustrated if things all of sudden were changed underneath me and affected me.

What if it's a triplex that needs three of a lot of expensive things, asbestos abatement, discover there is soil contamination because it used to have a small gas pump and holding tank under the driveway from when the 3rd unit used to be the driver's quarters in the early 20th century and it's leaking into the earth (I've actually come across that) and it totals way more than $65k?

if so, ask for closure reports for old tanks(3) check condition of spill buckets and make sure they are monitored. if not, should collect samples from around those structures. they often get dinked by snowplows and vapors may escape then condense into soil.(4) has property always been on public sewer since it operated as gas station. if not, did they perform auto repair?

Mainstream media has been reporting about it nonstop for the last few days, stating that there's just been the first case of person-to-person transmission on US soil.

Tx has different soils. 

I would figure all the bookkeeping, phone calls, coordination, etc. wouldn't need to have a license to perform those acts and you could just sign a contract per say with the owner saying I'll provide X services at X fee that I bill you for every month.I even considered going underneath someone else's broker license and just build up from there but the fact that they are going to take a big percentage of my already small percentage off rent just irks me when I'm willing to just build off my systems that I have already built/tested. 

The house had outdated carpet throughout and luckily there we nice hardwood floors underneath which we had sanded and stained for about $3000.
