FHA Appraisal Advice

[Luiz Souza]

I've been working on a SS with Wells Fargo ( FHA) for a few weeks. No double closing - I am planing to buy the property, hold it, clean it up maybe do some minor work and unload it after their 30 days. The appraiser just called me and I will meet him there next Tuesday or 3 days from today. House is located in a very nice area but is the least attractive in its current condition. Several necessary repairs including roof, lots of updating (about $40K to $50K) and the grass was up to my knees when I was there a few days ago. Any advice on how to handle this appraiser (other than the typical influence) so I can get a good number in my favor? Is FHA still going 82% of the appraised value or has that changed?
Thank you.
