The biggest thing I have encountered in numerous inspections is chipped or flaking paint in pre-1978 homes that have children living in them.

As we have 100+ year old trees on the property, as well as a pond and year round stream, I think it could also be used for a tiny-home or tiny-office (commercial) community, which would allow me to maintain control of my property long term and providing recurring revenue to me (my company). 

When my places with section 8 tenants are inspected yearly the inspectors just want to be sure that the paint isn’t flaking and thereby causing a situation that a small child may ingest the paint chips.

It wasn't a good deal $90k because of the age, weird layout, and the bathroom was tiny. 

The paint is chipped so I'm assuming there's lead paint and there will likely be asbestos and lead pipes for plumbing.

The rehab estimate seems very low and the ARV seems really high in my opinion, just based on a tiny bit of research looking at what this property was listed for recently (it hasn’t sold), and what the surrounding similar properties are worth (~$250k).

I believe that the residential real estate brokerage industry should be a tiny fraction of its current size, with far fewer agents and total commission dollars paid.

Now I just have to chip away at it everyday!

You're looking for finishes that hold up to wet glasses and don't chip, upholstery fabrics that don't stain, and furniture that doesn't sag or break.

It takes about 10 years of never missing a payment, using light leverage relative to your income, and using a tiny fraction of your available credit card limits.
