@Nick Thomas Hey Nick here are some items you should look for when walking through (with seller hopefully)!
Important question to ask the seller, "What type of repairs are needed on the home that I should know about". Very important that you ask this question.
When walking through the property, Look for a functional layout, Roof condition, Type of plumbing Galvanized, Copper, plastic? Soft floor around toilets, tubs, & appliances bounce on your toes in those areas. Check for construction materials that might have asbestos, Popcorn ceiling, old flooring, siding. Check if wiring system is knob & Tube, Aluminum, fuses? Those are some of the major areas. Some things look really bad on the surface but are easy cleanup. This is where you can create value!
You can download a house inspection sheet from google or read J Scotts book on Estimating rehab cost.
Lastly do you really want to become a long distance landlord on your first deal? An assignment will probably be your best option!
Good Luck
