They gave me the confidence I needed to jumpstart my journey into real estate investing.

Please don't let/use your obvious insecurities and lack of confidence to persuade another individual from trying something that may very change their life.

As the others have said the only way to become more comfortable with the situation is to have more confidence in your numbers. 

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

I'm also trying to be realistic with myself, I dont have the confidence to grab 8 properties or anything like that.

People want to hire a confident smart realtor to negotiate for them not a pity story. 

Cherie,Thanks for the vote of confidence.

It will save money and give you more confidence.

The biggest question is, can this property bring a sale price of $395k (or at least $390k) with a high confidence level and you will only know that by running the comps, getting professional opinions, and nailing the finishes and curb appeal of your product. 

I was very fearful of that initially, but as I became more confident in my abilities (and built reserves) I use my HELOC now.
