The seller has countered with the following conditions:- Loan to value (LTV): 80%- Earnest money held by seller's recommended property management company- Final inspection within 1 day of closing- Commission paid by to buyer's agent is 2% of final sales price.I'm seeking advice on how to proceed, as I have some concerns:- Why would the seller request an 80% LTV?

The amount and type of data they collect for "free" use is concerning. https://innago.com/privacy-policy/

What’s more baffling is that, instead of rectifying the issue, Mike provided access to the wrong account – the unused and unknown one – and eventually led to the cancellation of both my accounts.This experience not only highlights serious issues in their customer service but also raises concerns about their internal account management systems.

Beginner mistake ?   

Now, I understand that HELOC should be used for short term financing purpose and I am concerned that I may have made a misstep. 

For us there is no perfect property to manage.I am more concerned with the owner. 

What concerns me most is that statement: "I have yet to have a conversation with a seller"Here's the truth: It'll probably take talking to 50-100 prospective sellers before you even have a shot at getting a deal.You don't get to change that.You do get to decide how long you'll take to get those conversations completed.Reach just 1-2 sellers per week and it'll take you a year or two before you get a deal.Reach 10 sellers per weekday, and you'll likely get a deal within a month!

If it was just an email (again have not seen it) that says they are pausing with no explanation etc. that would be a very big cause for concern.3.

You pretty much validated my concerns with purchasing or rehabbing within certain Class standards.
