I am going to need a little help. 

I told him my fee was 30k per duplex.. so that was my listing agreement  330k each  30k flat fee commission.I took them all to the SF bay area and sold them all in one weekend.. they closed up over 60 days.. so that was a nice 660k in COMMISSION revenue for that quarter.. now I had at least 100k in expenses I had to  front 50k for marketing the event.. but it worked..

There are nice and bad areas everywhere, I believe you should avoid parts of Santa Ana for sure.

I have read many books on the topic, but it's always nice to hear from an investor. 

What size/configuration are each of the units and is this in a nice area in West Chester?  

For me it's all about having a great cleaning person/crew.Homeaway and Airbnb make it easy to keep an up to date calendar, accept payments, refund security deposits.Then nice to have are automated locks (I still use a lockbox), security cameras, wifi thermostats.You need great pictures and descriptions, you need to be responsive to inquiries and issues.You need a great location so that you have demand at your property.I think this is the Cliff Notes version.Take up Lucas Carl on the phone call.

Nice to "meet" you.

I have been able to keep up with payments on the 0% card, but it's definitely a nice safety net in case you can't get your balance to zero in one month.

But it's a nice new'ish 4 story building in a hot area of town.   

Taking the most out gives you options, leaving cash in there is just money you'll have to borrow later anyway OR WORST, you won't grow enough to need it.
