It's just financing the property post-closing.

So it really comes down to risk management and how comfortable he is with debt.

Since you own a single-family, your first decision will be what to do with that when you do decide to buy another property? 

With states becoming stricter, how are yall still managing to wholesale?

Here are a few simple and free ways to learn: Go to real estate meetup groups, attend open houses and speak with the agent there, inspect FSBOs (for sale by owner), walk your area, and speak to people tending their yards.The idea is to engage with other people and ask, Ask, ASK questions about their experience with the local market.Some other ideas: find a home inspector who will let you tag along in a property inspection, and absorb what they are looking at and why.Your mindset and enthusiasm for learning about real estate will open many doors for you.Good Luck!

@Rick Albert is right on and gives good advice.I'm actually wholesaling a property this week, but this just happens because I am in the game doing flips, developments, and rentals. i would never try to make a business out of it. 

I sold a property last year that required the owner to get a certificate of nonconformity to be a legal two family.

Or your can buy multiple properties with small mortgages.

Just because the home is renovated, does not mean the market in that area will reflect a higher value for the property.

The neighbor didn't want us to build there and he ended up buying the property.
