You are like many others who are getting started and unfortunately your generation is screwed because of the amount of spending is older generations have done and put the debt on you which also has led to record inflation.All you can do now is plan for the future and don’t force things but invest wisely when the time is right.

it will be a corporate/wellness retreat/short term rental destinationI need land that is close to the Action, but not too close, and preferably comes with two single family doors already built, so I can take advantage of Fannie Mae owner occupied loan and develop the rest of the land on my own and with private funding.Is Columbus a good market for this strategy?

Credit cards have the same limitation on the amount you can borrow and will likely end up costing more than private lenders.

I am wanting to be able to stop working full time sooner than later as I would like to be able to spend more time with my family and enjoy life. 

--------------------------------------I don't think it prevents you as an owner from initiating the action.Personally, I wouldn't have any moratoriums on private transactions.  

Meet-ups via local groups or via zoom calls or private REI clubs/groups.Asking a seasoned agent in each city/county as well as a Banker/Loan officer will also help put a plan together.

For my area it isn't worth going the extra mile or spending extra money for something big and luxurious.

@Katie Southard This is the floor plan. there is another but that does not have a separate car garage and has private entrance only from the side.

The two most common exemptions are the exemption for intrastate offerings and the exemption for private placements.  

Should you decide to do this full time and do more than 1 flip at a time, private lending and fix&flip loans will be the way to go.
