On Friday, an essential component of the refinery broke down. 

Or some tenants put in those dreaded bleach/chemical "drop ins" that corrode the rubber components (ruining the seal/flapper and more).

It has a Quickbooks like component to it that allows me to manage my books.  

.- Typically, the most expensive component is the replacement reserve, but there are also HUD inspection fees, a phase 1, an application fee of 1/3 of 1% of the loan amount, MIP if over 80%, and audit fee, etc.- HUD 223(f) loans go up to 85% LTV on a 35 year term-Typical PPP is 10 years.

People and their needs are important components of this business. 

For instance, if you could sell the home today for $200k and the land is worth $30k, then the materials are arguably $170k less land improvements and foundational components.

Are there any environmental issues?

Linoleum is quite different than vinyl:  first it is not a petroleum product, but is made from entirely renewable components (linseed oil, pine rosin, wood flour, cork, gypsum); it is naturally antimicrobial {one reason it is used extensively in places such as hospitals, day cares, nursing homes, etc.} and it is quite durable. 

Keep in mind that it does actually take money to get into wholesaling (in the form of marketing mostly), it may not be a lot of money you need but it's still a necessary component.

My brokerage has a property management component, I would be happy to put you in touch with them.
