I’m building a tech solution that should drive more buyer leads to an agent’s pipeline. But to build this I will need access to NAR APIs. Is there any developer here who can share their experience building with the AP...

We want to buy an arcade machine for our STR that plays a bunch of different games.

My nephew when to Cornell and played football. 

Yea this is a long-term personal play more than a strict STR deal. 

Lost in all of this has been the significant role technology now plays in listing and selling real estate.

My humble advice to anyone attempting to do creative finance is:Creative finance is for experienced investors who have access to capital if anything goes wrong.Learn the lawsDon't use a contract "off the internet", laws vary by state and are also regulated on a federal levelLearn the financing techniques correctlyDon’t skip parts of the processDon’t ever do a “kitchen table” closingUse the proper deedAn attorney can help you with the legal work, but the rest you are on your ownYour guru will not bail you out“Investing” in someone else’s deal by providing a small 2nd loan so the “investor” can pay for “cash to the seller” and for “closing costs” so he can do the deal is a very bad planKnow what problems can ariseLearn the responses and solutions to problems before they are neededKnow everything there is to know about Title and what that meansKnow who a "protected class" individual isLearn the "back doors"Learn human natureUnderstand timelinesUnderstand regulation enforcement (some of these "mistakes" have a 10 year statue of limitations ( they can charge you 10 years AFTER you do the transaction) and carry hefty fines and possible imprisonmentThe court doesn't accept "I didn't know" for an answer"Know that the source of the lead plays a serious role in some states and federallyKnow how much of a "profit" pushes the boundaries to invite an investigationYou can be sued by the seller if you don’t do things correctlyYou are automatically at fault if an investigator or attorney or regulator gets involved.

Should I play harder and get into land development?  

It’s stable cashflow and long term appreciation and tons of accelerated bonus depreciation on taxes. like most anything in real estate it’s a long term play. 

I have seen these circumstances; people die, go out and buy a car, lose their job, etc… Just my own two cents, I’m not an attorney, just play one on TV

You don't want to start playing sides here and getting involved in these kinds of debates.
