For anyone who is flipping a couple houses at a time, Excel is unlikely to be a good choice for financial management just based on the sheer number of transactions and categories that need to be tracked.As for your suggestion above, personally, I like to reconcile each of my businesses every day (I'm a little bit OCD :) ). 

Here is a good article that I came across before when delving into scraping Craigslist:http://ghostproxies.com/blog/2015/09/the-ultimate-...In the article they do talk about a few different options for you to use.Suffice to say, your choices are either to pay someone for their software/service or you need to dig in and get dirty with some of the free code available.

Marysville is a good choice!

If I was you, I would seek out a small local bank & try to obtain a commercial loan for each property you want to buy  .If you can't do that then I would seek out private money from somebody that you know or know of.I would also strongly suggest trying to get the owner to finance if you can.There are lots of ways to get money, but hard money lenders should probably be your last choice.  

In other words if he wants to just keep staying there and thinks he can get caught up  on rent you will only have one choice.  

(Buy, rehab, rent, refinance, repeat.)Your choices: Use that HELOC as a down payment on a 4 unit.

I sometimes do this at lease renewal time, offer them a choice of upgrade (of course this helps increase your property value AND make tenant happy.  

I spoke with the head of Cobb County,  and was told I had a choice to zone back to R-20 or LRO (Low Rise Office).

Excellent choice -- both of profession and community. 

So finding property on my own is a wiser choice you'd say.
