Consider how it will be used and if the floor can function as storage, rec room, family room, extra sleeping space, etc.From what you've shared, my concern would be the "hills" that may cause a tripping issue.

As previously stated as long as you are getting per paid hour or flat fee for your advice you are not an agent.

I've identified hopefully like mr Henry says, start small and make your big mistakes early, a small town in TX that seemingly could use more storage.

Im a college student currently working on my capstone project where Im aiming to build a property management software.

To provide an example, I was previously employed in the legal department of HHM, which at the time was a an affiliate management company of a publicly traded hotel development/operation company where we managed  the portfolio of  hotels as well as provided 3rd party management services.

1) You mention the PMC did a poor job screening the previous tenant. - What specifically makes you think that other than the parties and damages?

@William Coet it’s a different business model altogether.I love highly desirable areas that attract highly skilled high income college educated workforces.They tend to be more liberal and therefore the landlord tenant laws.The percent of their income that goes to rent is typically much less than 20% so a rental increase of 5-10% is nothing to them.They are typically lower cap rate areas and therefore every dollar of net operating income that is earned is explosive to the underlying asset value.

Financially, the numbers make sense, but I need to have a proper inspection since this is my first home (and I'm going unrepresented) and the house is built in 1915 with some renovations that were clearly done by the investor selling the property rather than a professional.Question: Although  previous owner has owned the property for 3 years and rented to tenants previously, should I be concerned that the legal zoning is only for SFH?

We would stay in one of the units until the youngest went to college, or moves on.

If the taxes were increased and the escrows that were collected up to that point were insufficient to cover the new tax bill, then your future mortgage payment will increase by an amount that will cover the new tax bill AND make up for the shortage from the previous payment.
