If you're looking for the all-in-one I'd go with a PM software (others have suggested some) and do what you can with it.Then, as you grow further, look at more sophisticated/expensive options.

When you are getting into raising big dollars from sophisticated investors they are going to want to see a track record and a well thought out and detailed business plan.

from the little I know and its only because i have brokered 50  100 unit apartments the buyers are quite sophisticated and have a lot of cash and have their lenders lined up.. 

Since they are advertising, I assume that they only deal with accredited or sophisticated investors, as well.  

But the other question is are you sophisticated or accredited?

One land speculation I bought 4 acres in sonoma County CA ( wine country) in 96 for 27k it was unbuildable at the time ( could not get a septic system on it) Well city grew to us The Graton Casino comes in right across the street and we sold a few years ago for over 2 mil to a land assemblage investment company.

Just looking at their website,  there is no useful or helpful information that a sophisticated investor would normally require (to even give them a chance of being considered).

People still think it's a junky casino town which is just not the case anymore. 

That makes me nervous - because if the investments could be proved up to sophisticated investors why hunt for the guy who gets excited seeing 45%?

It also requires gaining a level of sophistication and knowledge that not everyone has the time, inclination or ability to do.
