Set up a shooting range in the back yard with old appliances, broken vehicles and mannequins.

So fixing and keeping or selling and paying the tax are about a wash.So if you want the better finance decision it would be to sell and 1031 exchange into a vehicle like a DST or TIC if you want passivity and fractional interests. 

Are there any subsidies available for efficient energy options that you could avail of.Another related way to increase NOI whilst gaining the marketing advantage of being environmentally friendly would be to offer fee based electrical vehicle charging stations. 

I ultimately want to utilize BRRRR as my vehicle, but I have very little of my own money. 

There can be instances when there are transfers/contributions between a member of an LLC and its member.The great thing about LLC's and partnership vehicles is that it is not considered a "taxable" event when you transfer property from a member to the LLC.I.E.

Speaking purely on what kind of real estate vehicle I'm most interested in doing; my dream scenario is to buy apartment complexes and own the property management company that runs them. 

The only "cost" to this strategy is the difference between my mortgage rate and my HELOC rate (eg. 4% vs 6%) to have the meowny in a different vehicle.

I used 2 vehicles I owned as collateral for the down payment.

The end goal is to have have to have enough parking for a single vehicle per unit, to separate the water and electricity, and to convert the single family into a duplex. 

Also, I need the living area to be at least 7ft off the ground due to 100 year flood plain so thinking lower area would be for vehicles.
