There are creative ways to use VTB and combinations of other JV to help you get the funds. 

Both units are occupied and is bringing in a combined income of 4,000 a month.

In my opinion this would be a much better investment of your time towards getting out of the situation of trading time for money, than a real estate broker's license.In my portfolio I have a combination of directly owned real estate and passive.

The properties currently have tenants, with a combined income of 4325/month.My question is, how do I make this deal? 

This also ensures you get your money back in full but could also benefit from the profit.Of course you could do a combination of the two (anything in between) where you still charge interest on your loan AND you share in the profits.The way you craft the financials is totally up to you guys and what you feel comfortable doing.Hopefully that helps. 

I think there is a lot of potential in this combination.

Or maybe combine it with a list of top items new investors need to know. 

The combination of long term tenants and AirBNB income has certainly been helpful, particularly with regards to diversification during Covid. 

Cap ex and maintenance each month combined are $50.
