If you want to be more on the knowledge/digital side of skill, marketing is a good place to start.

I can't tell you how many properties have units easily convertible from 1 bedroom to 2 bedroom units, units with favorable dimensional standards which can boost rents with no photos to showcase these attributes, assessment square footage that is not correct,  upgrades not identified in the marketing materials etc.

I want to understand how to structure the finance terms.if for example the house is on the market  for $200K1. how much do i ask for down payment2 going interest rate?

People were talking about how real estate agents can't find off market deals@Bill Gulley said it.

the reality is BANKS left the fix and flip market after the GFC.. very few will do them unless your a premier client of theirs with a  long track record and they are doing them as a service to you. 

In regards to your markets you mentioned, TX is likely going to be a better market for appreciation than OH. 

I have found very little deals thru an actual wholesalerRe read what @Thomas S. wrote If you don't take the time to educate yourself, create your own business plan,and know the metrics of buying selling rehabbing wholesaling,marketing ,etc you will just be throwing money away like the hundreds of newbies flocking into the business 

This is the best terms I have seen in the market thus far.

I like SFHs because in some of my markets they have a huge potential for upside and appreciation.

I'm now in the market for an income property or two!
