Again, just be careful, and make sure you have enough reserves, an exit plan, and the mental fortitude to persevere if something goes bad.

I need to use the income to boost my debt to income ratio but the lenders I have come across won’t let me use the air bb revenue.

If your hope is that you will bring a partner in with great credit to boost yours you may find that the end lender will deny your refinance request based on the lowest credit score for everyone in the entity.Hope this helps. 

I am personally going to be handling the leasing of this property - it is my trade at Newmark and I was able to bring my cousin into the deal to open up his pop up clothing brand until we find a real tenant giving us an instant NOI boost.

You have an advantage over a lot of other folks right now in that you are living for free which gives you a golden opportunity to be able to pay off your car as quickly as possible and boost your savings account.

I will not rent my property to anyone with this mentality or assist with the enabling of neo nazis, separatists, confederates and other far right extremists who believes any conspiracy fed to them.

If your parents or any other friends/family have great credit scores with long history ask if they can add you as an authorized user to their credit card(s) which will help give you a boost, but otherwise work on getting your own credit card and consistently using it in small amounts and immediately paying it off.Also work on saving as much money as possible so you have reserves and money towards a down payment as soon as you're ready to make a move.  

I took a mental break from real estate for a bit but I am ready to get back into the game.  

It sounds like you have a good system to generate cash & good rental properties, maybe now you need a system to find and hold properties that works for you.It's a good idea to mentally separate the two halves of your work:  the "business" side: buy/fix/flip properties to generate cash, and "investing" side: buy and hold rental properties and other assets to build your cashflow. 

They think they're super-special mentally, all the horsepower upstairs in the world -- but they're not and it's laughably obvious at times.
