I am just looking at numbers provided by Zillow.I agree that the cost for most items such as a Roof, HVAC, Piping will be similar between a cheap home and an expensive home.

It needs a full rehab, roof, garage, appliances, everything. 

Look Any lender or partner is going to need you to bring something of tremendous value to the table .

Although instead of knowing about roofs and rehab.. land folks need to know about:Zoningwhere is the power  is there internethow deep are the wells or is its an area that water is super toughDoes it perc. and or how expensive are septic systems.Wetlands Etc.Now if you target land with all city services then its just dead simple.. figure out the retail value and buy below it and do your flip..

With fresh paint throughout inside and out, brand-new roof, dual HVAC systems, updated water heater, stainless steel appliances, lighting fixtures, outlets, countertops, and PEX plumbing just to name a few.

Handsoff experience, because I am the person technically managing their property I will deal with all the hassle and headaches that come with being a landlord, and only would contact them for emergencies like the roof caves in or something, I feel like there's alot of benefit for the landlord they still profit from my success and still profit even if I don't do well.But thank you Corby, yea I didn't know how to phrase that I want to host their property towards travel nurses without mentioning subleasing, but your approach makes alot of sense, especially " help landlords lower vacancy and are looking for feedback, ask if you can buy them lunch." 

Look for homes with updated systems—new plumbing, HVAC, roofing, and windows are essential for long-term value and tenant satisfaction.

I want to point out that I’ve noticed his tone in emails can come across as demanding or even a bit rude.For examplez: I see how he writes to the group—always polite and full of "thank you"s—but when addressing me, the tone feels far more demanding.Would it be okay to respond with something like this?"

Quote from @Ariel Nixon:  Yes it is always too good to be true when Cash Flow is through the roof. 

Its extremely important when running tighter margins like what you're talking about to focus on age of HVAC, water heater, appliances, roof, etc.
