Other than access to cash the biggest obstacles are the time it takes to perform the research and the ability to handle the inherent risks of buying property at auction that hasn't been available for inspection.

Have the ability to purchase HUD homes with out having to pay a realtor to just submit a bid for me.

Do not assume that your ability to be a successful RE investors if tied directly to this one pot of money.

That strategy works best if the park is too small for a serious onsite team and you have the ability to watch over the manager. 

Another alternative that has not been spoken about is a ROFR and a leaseI wrote an article a while ago about "Why a ROFR is better than option for an owner" (right of first refusal)@Dwayne George You should also read the statute in North Carolina about any lease purchase or lease with option as they are very strict in NC with owners.A note and a mortgage if free and clear should be done with an attorney.Don't do seller financing without a large down payment and really checking on their credit rating and  their ability to pay (net income in vs expenses out)

When you are just an employee trying to do your job they seem to be more understanding that you are just enforcing the rules because its your job.The ability to separate my business assets from my personal assets.  

I have no idea what future guideline changes will bring, but now there is the technological ability to actually exclude those debts, should it ever be decided by the powers that be that this would be a good idea, because the trended data is right there on the credit report (actually started appearing, in my office, a few months ago).

I suspect they ratified the contract so commish is owed.I bet this just blows over its a small claims matter most likely anyways.. but one can sue for performance I did that last year and won.. my first ever but there was substantial dollars involved.I put up over 30k to pay back tax's and the seller would not sell.. so I sued for performance and won.Now I had to on the date of closing put all my cash into escrow 100% of purchase price and it was a tidy sum.. and it sat there for 18 months while we went through the court process.. the Judge gave the seller every opportunity to defend but she just went completely dark and lived there 2 years for free. but I know thats an extreme deal and most folks ( buyers will not go to this level) and or have the ability to do that since they need a loan to buy.. but there is a lot of cash out there so we can't make that assumption that the buyer does not have cash to come to closing on the close date and make a demand.  

This is usually from improper install which then voids any warranty that came with it, thus leaving the home owner with a bill. 

I do think getting your license can be a great tool because it gives you access to the mls, education, and the ability to access the listed homes on your own.
