I'm a cash buyer and I have filled out at least a half dozen forms that wholesalers have provided for me.  

That's half the equation.

We originally wanted a duplex and live in half, but all around here seem overly inflated on price 150k or higher.

Home Value as is $125 KPurchase Price - $70 kThe owner I would be purchasing it from is losing it to the bank and wants to continue to rent with the option of purchasing the house back in 5 years or less for 90 K.Keep the owner in the property as a tenant, but don't make a long term commitment without having a good real estate attorney draft up a contract that will protect you.That would be the easiest fix in my opinion.  

probably one of the easiest ways to find deals is to call all the signs on poles or in yards that say we buy houses in your area call them immediately and get on their buyers list,most if not all of these people should be wholesalers and investors in your area when they call you with deals run them through the BP calculators and make sure they are deals that your investors would buygood luck @Lindsey Turner

Or better yet, pick another town, split the package in half and diversify.Having personally done a number of properties in Detroit and other surrounding suburbs in Wayne County, I would say be super careful before you spend your money on a package without doing a bunch of research.  

If you cannot trust your team, you will be left with a half finished liability.

I would build an extra half bathroom but it would destroy the architectural integrity. 

I want to do the whole rent half and live in the other half deal.

So I'm looking to learn to invest about a hundred grand a year, maybe up to a half a mil over the next 5 years.
