Mama lost confidence in you, so go earn it back.

Most importantly you need to convey confidence and assurance you are a player and not just wasting their time.

I feel that I am confident in finding good deals and have basic knowledge of what to look for in a property.

This feels risky to me because I’m a not 100% confident about the numbers.

I am now a very confident home inspector working for a company and I have established a great reputation with agents in my area.

The more you study and research your niche, the higher your confidence will grow in your purchases and the uncertainty will be out the window!

Now to up my discipline and confidence and take the big step.

Buyers place values on income streams based on all kinds of stuff (alternatives, interest rates, money supply, economic conditions, confidence, risk, location, supply, asset type, upside potential, demographics).

You may or may not have the technical aptitude, confidence, or your application might not really be feasible here.3 - Up-size your system - this might be a larger blower motor (check this first) - and if that's not an option, then you can move to up sizing your furnace/blower (if you're running a 'typical' split system).That's all I can think of. 

So, the correct answer is; there is no correct answer.You, as an investor have to do what you are confident doing.
