Because we needed more time to gather quotes for the work that needed to be done by contractors we trusted, we extended the deadlines in the Property Inspections Notice (PIN) on multiple occasions so we had enough time to better understand the issues and also protect the buyer's deposit.I'd get a few good contractors on hand, have them give estimates (see if they can even do it using the inspection report if visiting the property isn't possible) and have the seller compensate you an amount that you think is fair (it may not cover everything, but is it enough to still make the deal work?)

If the fair rents really are $5,000 a month, then this is a solid long-term play.

I'm planning to buy a SFH in Huntsville in the next 2 months so I'm looking to understand more about the area.My goal is to buy in a B/C class neighborhood for a deal that is expected to be cash flow even.

It's a legal issue determined by your state's laws, so you may want to consult with a landlord-tenant attorney to get a good understanding of that before you make a claim on the deposit.

Once the renovation was complete, I helped the client with tenant acquisition and long-term rental management, turning the upgraded property into a sustainable income-generating asset.This project not only increased the property's value and rental income potential but also provided the client with a solid, long-term investment in the real estate market.

Plus an investor/agent knows and understands the numbers, they can estimate rehabs more accurately as well. 

I would speak to contractors to understand what this will cost.

From my understanding it can be... legally anyways...

You will need to narrow it down a bit before anyone can give you any solid advice. 

I learned a useful lesson that I have kept with me throughout my work life.Our second deal really made us understand how important it is to negotiate.
