I'd just like to get a sense of some different scenarios that might be appealing to them, while mitigating my acquisition costs.

I would also figure out the cost between now and next renewal and where you are related to the market.

Hello, Can anyone recommend a broker or a direct lender that I could get a large line of credit from to fund the down payments + closing costs on turnkey investment properties? 

Review their management agreement.

You will most likely pay more than market rate so take that into account.You will then have to get it all furnished which can cost a pretty penny.

They also manage over 1500 units as of now.

I recommend using an experienced agent to help you buy especially off-market deals to help avoid costly mistakes.
