I don't want to continue this process unless I have a faster solution or a professional do it for me.

Solution:  Only hire contractors certified and registered under the RRP rules and do the best you can to make sure they are following the correct work practices, documentation and clearance tests. 

keep in mind they were aiming for 5% and it still nearly eliminates the incentive for the only solution, new supply and maintaining the existing supply through value add programs. 

I ve been able to get a house around 80k and ARV 375k ... or even another scenario purchase  145k  wholesale 289k and buyer sold for 575k ... win win  for all , the seller , need it probate on a sudden dead siblings on other estate and elderly , no time for fixer upper, it was a win win  for all.and the cool thing , having first dips while acquiring the deals , if is juicy enough you can get it for yourself. also develop great relationships with other local investors , ( a great happy community , cos everyone is making money   and also providing solutions to distressed sellers) .   

I try to check out possibles and may drive by where they live and see if they really do and have talked to neighbors I have had owners tell me "don't to rent to them,"I will ask relatives or friends when I can if they would rent to themWhen Granny warns you off or an uncle says "you don't have to worry about money with them two and pauses and said you won't get any years back I didn't worry much ,had a few people who would find creative solutions to problem tenants if I was silly enough to get suckered in

Is there an all-in-one solution?

My guess is that behind such specialties as a solution to every thing that comes along, you'll find someone who lacks knowledge, manipulates others to facilitate a transaction, someone who will be defensive about what they do as an ethical stance, that attempts to use loopholes or convoluted strategies as a marketing aspect convincing others that they can avoid matters that may restrain business.

Looks like you found the ideal solution.

If you plan to do any kind of marketing for this property, you'll find that you get sellers of all flavors, and the solution or exit strategy can be just as varied.Not too long about, we had six seller appointments in one day.  

Your in a tough situation with no easy solutions that are not costly.
