This is a typical roof drain.

I also liked the fact that it was structurally sound with concrete block construction, a tile roof, and high elevation.

For the first part of your question even if you were working with a realtor, I don't personally know many that have a true pulse on rehab costs and I wouldn't make any investment decisions based on their rehab cost projections.My suggestion would be to study how to evaluate the Big 6 rehab costs: roof, siding, windows, HVAC, electrical, and plumbing. 

We are currently looking at a HUD home in Georgia - I have a couple of questions and can’t seem to find a definitive answer - The home is currently in the OO listing period - our plan would be to buy the home doing extensive renovations (the home is in a “Historical” area so renovations have to be approved) once completed we plan on living there full time - it could take ip to a year to complete or longer I don’t know  - as I see it the OO designation is to be the OO for a min of 12 months - is this after the home has been renovated or after you close on the home - though the house could probably technically be lived in now it does have some water and roof damage and needs complete redo of electrical and plumbing - for me to deem it safe - so not really livable by normal standards - but no way it would be livable in just a couple of months - any thoughts or an actual answer to the OO rules 

Roof, HVAC, water heaters, flooring, etc.

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." 

Section 8 demand in Cleveland is through the roof, but unfortunately they don't actually pay that amount. 

For instance, if hail damages your roof, you’d receive payment based on the roof’s current value, considering its age.Replacement Cost: Covers the full cost of a new item.

If they have a good roof, I use a company that used to send someone out to do a roof inspection (at no cost to me). 

When there is a vacancy, a leaking sink, a drip from the roof, a fallen branch from a tree, storm damage, a rough tenant, a potato down the toilet...whatever expense comes up in the future, and they always come up, that is what the cash flow is for.
