Home is rather large, in a corner lot and with an RV gate.

The advantage to a 3/2 or smaller is that it will appeal to a lot of midterm rental demographics (remote workers, divorces, people building new properties, etc.) and the American family is shrinking (fewer and fewer people need a large home), so if you want to stay rented in the midterm space, a 3/2 or smaller is best.However, appreciation is a different conversation for a different day.... 

In just the past few years we have gained excellent traction having completed 12 real estate private equity transactions totaling $3.8 million averaging 30% return on capital investment.

The level of risk you face with a lease option depends in large part to the type of lease option you are doing.

I like the construction aspect of flipping and large lump sums at the end.

Are there any good websites out there that anyone recommends I try? 

Adjustments are largely judgment calls.
