Their analysis of the after repair value and desirability of the area will be invaluable if you don't live there.

I could of course keep repairing the slate when leaks appear every 2 years in different parts of the roof but it's a little stressful when we are on vacations and I think I'm time for a replacement.

None of the properties need major repairs.

I am really afraid about hiring a realtor who is not truthful about my home value after repair.

Higher/more frequent repairs etc.... thoughts....?

Then repair the damaged areas.

@David OlsonI am in no way an expert at this but I believe when you are making a cash purchase the main team players are:Attorneys, Title Company, Inspector and Appraiser (occasionally)Attorneys: Using legalese to get the purchase contract in writing Title Company: Perform due diligence to make sure there are no liens against the propertyInspector: You already covered thatAppraiser: To determine the price of the property at its current state and after repair value.

I was able to finance up to 80% of the after repair value. 

The best terms I have seen my clients get is a $50 / unit / month flat rate fee for management, and the worst was one property management company that quoted 10% per month of collected income, plus a 1 month rent "lease renewal fee", plus 10% of any repair costs.

HMLs can do a % down of the ARV and finance your rehab too depending.Refinancing usually has a 6 or 12 month seasoning period depending on your local credit union/bank and usually they require 1 year lease.Lenders- if you are going conventional, and have properties in your target market that would finance (ie no roofs that need to be repaired or major mold issues) then just start talking to local lenders and see what their requirements are.
