Is there a way to structure the relationship so that I get passive income that offsets my passive losses, thus resulting in no tax owed?  

Unfortunately I was told they are not the same category of income so they don’t offset each other. 

I am pretty good income and this would still take at least one year for me to purchase. is the idea i just purchase 1-2 a year of this standard?

Basically, the charitable remainder trust is, as Bill pointed out, irrevocable, and will pay you an income over your lifetime and distribute the remaining funds to whichever charity you like upon death.

I strongly suspect your best move is to roll the TSP to a Traditional IRA and convert the IRA to a Roth, using non-retirement dollars to pay the income tax, even if you have to borrow the tax liability. 

Each STR property I acquire must meet two financial benchmarks: a gross rent multiplier (GRM) of 5 or less [Property value divided by projected income must equal 5 of less], and compliance with the 1% rule as LTR, which serves as a backup if regulations shift or if there's a decline in STR income.

But I am single so there is no second household income.

When creating your criteria, it is important to focus on the evaluation of the following qualities: • Capacity to pay: Does the prospective tenant have enough income to afford the rent and other expenses involved such as utilities or additional costs such as parking or storage? 

If you are wanting rentals who cares about up or down 10- 15% when you are earning 10- 15% net income. 

Sure, you can (and I do) flips here and there, but wealth is built not flipped 20% a year NET caps, 40k a month income is much better than a mill.
