However, we had a pipeline going from years already syndicating as well as investors.The hard costs of getting up and running were about $5000 for the software/site development and $10,000 legal fees for PPM, Operating Agreements, Investor Subscriptions, SEC Reg D filings, and 10 state filings, and general legal consultation as to best way to set up operations and or compliance issues.

Can anyone please recommend good property management software?

In other words, there have been a lot of expenses associated with the typical process of buying a property (mileage, legal fees for LLC formation, property management software, etc.). 

Read quite a bit too and feel a lot better now and believe I want to jump in the real estate wholesale niche to begin with and then gradually based on the experience & the type of deals I obtain, transition into fix & flip.But before I do that, I am a guy who likes to be prepared, have a strong business plan in place, processes in place, growth processes, manuals ready on what needs to be done and how etc etc...I would like to find out about what are the different software's out there which you pro's are using?

Can someone recommend some helpful but user-friendly software that will help me calculate the important financial metrics (e.g., leveraged IRR, unleveraged IRR, cash on cash, etc.) that I would need to know in buying small apartment properties (15 units at a time, for example).

Prior to leaving that career, you held a federal position for a year as a construction manager on projects ranging from a few hundred thousand up to $17-Million-dollar military construction projects.All during this time, you advanced your skills with CAD software that now allows you to produce high-quality drawings consistently and accurately, culminating from your experience of 30 years in the residential design and construction industry.

This might sound a little crazy but I actually liked my landlord software so much that I ended up applying for a job with them.
