I was particularly interested in accessing Conventional Financing for the both of us, having my cousin only applying for the loan meant only his income would be assessed for borrowing capacity and therefore the size of the loan we could potentially borrow would be limited.

You can offer to do a safety only inspection addressing only safety and health items around the home or an informational only where you're assessing the property through the inspector's eyes but do not have the grounds to negotiate after inspection. 

Put my duplex into forbearance at start of COVID and as I am gearing up to move out of forbearance I wanted to assess my options.I spoke with four different representatives and received four different responses.

Even if you eventually hire someone else to do the work (which you most likely will) having the knowledge will be VERY important for you to assess buildings you are looking to buy.

Once you get more 5 star reviews as well as respond to booking requests and inquiries very quickly, you will move up the list.I agree with @Patricia Steiner's assessment.

Another coverage that you should consider is "Loss Assessment".

However, since there's not a website that automatically assesses investment potential is a valid way, we've got chances!

Given that several of the properties are rented and cashflowing, how would I go about assessing the condition of those properties and what may or may not need to be done to them?

However, if you consider 10% for vacancy and 5% maintenance/assessments, I'm negative about $300 cash flow/year, with the benefit of holding it being in the $6,300 in mortgage paydown assuming 0% appreciation. 

Shuo, in my experience as a property manager, you won't be able to accurately analyze and assess the relative risk to appropriately rank each investment opportunity without knowing a given market and its neighborhoods.
