Using a professional to estimate repair costs

[Patricia Milward]

One of my neighbors passed away and left his house to a niece and nephew. The house sat for about 3 years because the niece didn't like the offers they were getting. Eventually a REI bought it , rehabbed it, and is now renting it out. I contacted him to ask about professionals he has used for estimating repair costs and doing construction, and it turns out he does this himself. He said he would be happy to help me if I find a property to look at. Should I offer him money or take him out for lunch or what?
