Ok but "should have known" and "did know" are two different standards, and unless the seller had a survey done before it was put up for sale that clearly labels the roof as crossing survey boundaries, I doubt you can make a case there for fraud ( which is what willful failure to disclose is).

Also, I really wanted the units to be up to my standard, but I think I spent more on them making them look better with upgrades, etc, than I needed to.

The painting should be completed within three months of the move-in date, and the Lessor will inspect the work to confirm it meets these standards.”This implies that the LL gets to determine that the paint job meets his quality expectation.”Per the mutual agreement between the Lessor and the Tenant, the Lessor has agreed to reduce the monthly rent from $3,200 to $3,100, allowing the Tenant to repaint portions of the house at their own expense.”this is not as clear as it could be, but could be interpreted that the rent is $3200 if the tenant does not paint the areas that the LL specifies to the quality that meets the LL quality expectations. 

This is because the envelope of the home was not built to modern standards and making functional living area can be challenging unless you have a lot of real estate to work with.

This is standard practice, but there are exceptions.

@Celine Li Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

The standards have been out for about a year and most sprinkler installers are 3 to 6 months out. 

.), which satisfies the "just wanna flip the standard channels" crowd.

Website is standard...the thing is, if they get your info they will literally harass you with phone calls from some place in India.

I used the standard Massachusetts Lease Rental application and it didn’t have any language regarding such.
