Or find a deal first then market it to buyers, then offer on the house and create an agreement with the seller & buyer?

There may be a couple of houses on the block that do not have driveways so this may not be the only one.

Unfortunately, my work phone is forwarded to my cell phone as I mainly work from home due to health issues. 

Sounds like you should go the house hack/FHA route.

I've dealt with this exact same situation, and ontop of everything I was dealing with the Section 8 housing authority because my tenant was a voucher holder. 

Since you mentioned that you are getting started, I highly suggest you house-hack (this is how I got started in Costa Mesa, Orange County).

The Yale Law Journal article, "Zoned Out: How Zoning Law Undermines Family Law’s Functional Turn," highlights this issue, noting that while family law has evolved to recognize diverse family structures, zoning laws have lagged behind, potentially hindering innovative housing solutions like co-living.Challenges for Co-Living InvestorsFor real estate investors interested in co-living, these restrictive definitions can lead to:Legal Barriers: Difficulty obtaining permits or approvals for co-living spaces due to non-compliance with traditional family definitions in zoning codes.Operational Challenges: Potential fines or legal disputes arising from housing arrangements that don't conform to local zoning definitions of a household.Market Limitations: Reduced ability to meet the growing demand for affordable, shared housing solutions.Advocacy for ReformThe Bloomberg article, "Why Are Zoning Laws Defining What Constitutes a Family?"

You know those signs that say "we buy houses for cash" call them and say you are investor looking to buy a flip. 

How much less will a potential buyer pay for the house, now that one "bedroom" does not have a closet?

But I quickly realized that scaling one house at a time wasn’t the most efficient path to financial freedom.
