Second I would like to ask is are there any suggested contracts that are better than others for both the landlord as well as contracts that I should use for my sublease? 

@Hunter Duplantis what @Gino Barbaro said is exactly what I was going to suggest.When you have vacancy is the time to experiment and apply your original thesis.I’m not trying to play Monday quarterback here but, you should be highly confident in where the rents should be well in advance of having a vacancy.That being said, after confirming competition rents on websites (I’d also recommend Craigslist and Facebook marketplace), you should be in alignment there.  

I own a wellness facility, but also invest in real estate, and help investors.

This method allows each partner to defer capital gains tax on their portion of the property.It's important to perform the "drop" (distribution of property to partners) well in advance of the "swap" (sale or exchange) to comply with the "held for investment" rule.

Where to get the most recent and accurate data for things like:Unemployment dataPopulation growthJob diversity and top employers in the areaVacancy rates (eg huduser.org)Property taxes and jnsurance costsI saw bp pro and reventure and a bunch of other websites provide some of this data, but i wonder how accurate and recent it is.

I'm here in Toledo and have my rentals here as well.

If the goal is to become a full-time flipper/contractor, then doing tighter jobs can help build momentum for a business, that will pay dividends well beyond just the specific house, itself.  

Also great deal as well for youHow is it dealing with voucher holders in duplex's?

If you can get a waiver of subrogation as well you will be all set.

Mortgage rates have kept increasing as well, that's why I put a range on negative cash flow.
