I know that you both have acquired a good number of properties in Vegas... may I ask what years you bought them? 

Only place it says that is in the loan docs which you don’t have access to.

I was denied access to them two times.

We can access the beam from the attic. 

Depending on what you lend against, this seems like it may be a tough one to acquire traditional lending. 

If you haven't - you may not be eligible to defer your taxes.You purchase price of the new acquired properties need to be above the selling price to defer all the gain.The sale without a 1031 will result in capital gains tax(0%, 15% or 20% depending on your tax bracket).The state will also tax you for the gain.

I have recently became a licensed real estate agent but have not signed under a broker yet or have access to the MLS yet.

Do I split up the money in some way, keep the high-interest loans and acquire more properties?

Decide how much money you have access to, & the zip codes, city or state you want to focus on.

You still have access to it.
