@Michael FriasI have actually done this not in Detroit specifically, but 35+ wholesales without ever seeing the property, it was while working for a real estate investing company, under an experienced investor who had more than 10 years experience investing, 10-15 VA's that I managed, and a bunch of systems that made this possible... even still it's not the best way to do wholesaling at all, and it wasn't my desired route but it worked at the time.The specifics as to why it won't work:You need to be experienced to wholesale properly.

This will require you to learn all the ins-and-outs of parks, to include filling up spaces, renovating homes, selling homes (along with licensing requirements), carrying paper, crafting the correct leases and notices, establishing the right park rules, proper tenant communication, metering of utilities, and the list goes on...

Look at it from both sides since there could be even more risk with a tenant staying if they haven't been properly vetted for example.

If the current tenants are under a lease, you need to wait until the lease is up for renewal to increase the rent (and make sure you give them proper notice). 

After that it’s a weighted average as follows (.75% x 7.92%) = 5.94% + (.25 x    8.00%) = 2.00 (5.94% + 2.00%) = 7.94%. 

A good CPA is worth their weight in gold.

I have a number of properties down-valley of Palm Springs proper, and did some research in Big Bear a couple of years ago. 

How much would it cost to manage the property in regards to dollar amount for paying a property manager and also your time and trying to finding a proper tenants have to work in 40-80 hours per week.  

However, since none of us know your particular rental property or even what city you’re in, we can’t answer your question with any degree of accuracy.I’m assuming your property manager knows your property and local market though, so you’d have to give some weight to the advice they’re giving you.

I just don't know what the proper steps are when buying the contract.
