Property had lots of repairs needed and sold as is.

Best thing would be to get started hustling for another wholesaler to see if it really is what you think it is.The only way to be a good wholesaler is to build relationships with sellers, know repair costs and ARV, and understand that each seller has a problem to solve and do not need a cash offer.

If I purchase a duplex and live in one side and decide to renovate the side I’m living in. Can I write off/ deduct my expenses for the renovation?I would be doing this to be able to rent it out in the future at a high...

Considering the high deductible on House B, I am only filing a claim for House A, and coming out of pocket for the cost of repairing or replacing the roof for House B. 

If you're accredited start researching potential syndicated deals- Some you can get in for as little as $50K; muitifamily, storage facilities, Residential Assisted Living..... 

In general I'm saving for repairs to the property, but we all know that this covers a wide spectrum.

If I don't make the repairs to the MH I won't be able to rent it at all.

Leaving you to move and store their items if required by law, clean and repair, etc etc.

First, you would need to subtract allowances for repairs and vacancies (a necessary prediction).

Let me know if I can be of assistance.
