I would slow down and think about your BUDGET, what you can get for $30k, and how you can increase your income.

But, for instance, I sent them a notice of rent increase effective February 1 and needed them to confirm that they have accepted the new payment terms through our electronic payment system, and even after repeated notices, they are not responding.

the property’s rehabilitation is scheduled for completion in 2025 and the rent will subsequently increase, can I proceed with a cash-out refinance based on the current rent roll?

The state laws (do not quote me) appear to not let these companies increase rates (or its not easy) to pick up the losses.

Quote from @Noah Wright: No, but here are some ways to increase ARV most dramatically:1.

By facilitating the closing process and leveraging a strategic marketing approach, we increased the property’s visibility and quickly found a buyer.

You already mentioned Mid term, which can be a great way to increase cash flow.

And over time, as those assets to make our product we sell had a fixed price, the dollar does not sit fixed, our cost of product increases meaning increased cash-flow.

When we create our business plan, we also include our exit plan.We'll only proceed if we can clean this up, acquire new tenants at higher rents so we can increase our NOI, which in turn should reflect our cap rate and profits.Since this asset class is new to us we will tread cautiously.Scheduled to preview tomorrow. 

Typically if demand increases and supply is maintained prices go up.
