But we were nervous.

Actually if you want to ask me specific questions that would be helpful as my general reply to about everything with this first project is "eye-opening," lol.That being said,  even though there were several times I wanted to have a nervous breakdown, the BIGGEST take-away from all this is I realized that I absolutely LOVE real estate.  

My wife and I are both a little nervous about chaining our house to some investment properties. 

Just a little nervous about actually calling them back and responding to emails.

He wouldn't show me two of the units, so I said I had to see the other two before I could make an offer.I'm nervous about the back taxes and how to handle that, how it would affect financing.

I have always wanted to own real estate and I now have two properties ,now my desire is to own a 4 unit rental and have been a looky-loo on all the real estate for sale websites.I get nervous when it comes to financing ,number one is the 20-25% down payment, is it always the rule to put down 20-25% on an investment or are there places to go that don't require so much and  won't require me to move into the property?

When I first started wholesaling(6 months ago) I really was nervous.

I figured I make more money renting each room out instead of the whole side as one to actually cover expenses and im nervous with the neighborhood i will get top tenants even tho the property itself is really top tier.

I have never been a landlord or homeowner so I am a little nervous about going ahead and jumping into a 3 or 4 unit building.2.)

I'm just a little nervous since it would be our only source of income as opposed to here I have my door business.
