Seasonality at the beach is dramatic, and weeks or month long contracts are easy to obtain almost anywhere in the South because of housing demand shortages, particularly in places like Charlotte (8000 listed homes, and 60,000 applications for those homes for medium term rentals).

There are some that meet your criteria that pop up but most need at least some medium level of renovation. 

The driveway will be 50 feet in length and 16 feet in width and if I use your $7 sq. ft. that comes out to $5600, which ain't bad at all.

Are the setbacks and lot width adequate?

I'm currently thinking of the following breakdown:600k in Fundrise (seems safe and low effort)500k in a triple net commercial property in a growing neighborhood in Arizona currently housing a BMO bank500k in a multiunit apartment complex deal with a friend and possibly including my brother who is also getting $2.5M300k in one or more local single family homes, Airbnb or long term rental (I think my current market has a lot of room for growth)200k in medium risk CrowdStreet investments200k in gold100k in cryptocurrencies50k for higher risk investments50k in cashI feel like stocks are way overpriced at the moment, and don't feel attracted to bonds (though to be honest, I haven't done a lot of research on bonds).

If they ignore that reality, that is their problem.Just from the outside looking in, Zillow Instant Offer appears to be operating as a medium in the underbelly of the wholesaler space,  not the retail agents' turf.Zillow is trying to vet the cash investors of not retail-ready homes for the sellers. 

Somewhere in the middle, is a happy medium, I think, as an investor. 

For Medium-term rentals, I just use a regular long-term rental policy since it's over 30 days.

I have been doing BRRRR for several years on small to medium sized single family homes.

There are of course generalist, but often commercial agents/brokers are very specific in what they do....hotels, big hotels, small hotels, restaurants, tenant rep, industrial, car washes, strip centers, land, office, medical office, small apartments, medium sized apts, large institutional apartments....and on and on.Is there not enough business for you locally to stay in business?
