I would than apply some creative financing trial offers; subject to, delayed settlement, hybrid offers, partnering with sellers, front porch clauses (this is where the seller pays you money to use as down payments), vertical break up - this is where you offer to buy the building and lease the land (this is a  seller financing techniques)  to mention a few.When I started to solve problems and help others, the universal law of reciprocity would kick in and I started to put together transactions that helped the sellers and me as well. 

Not fun, been there, it is a process of trial and error to get the smell out.  

I can enroll in classes at my local yarn shop or on Craftsy.com to learn to be a better knitter or I can choose to just dig through all of the "free" information available online, or see if a neighbor has time to teach me and be at the mercy of their schedule, and learn by trial and error.

All of which will soon be audited and trialed in court.I foresee a ton of AirBnB folks getting their a** handed to them by Uncle Sam over the next few years.

In Salem MA as @Karl B. referenced, there are multiple 1600s and 1700s homes - it's the place of the Salem Witch Trials.   

I just signed up for the free trial for all of them to see the differences and so far, Property Radar seems a little clunkier to use and even gets stuck once in awhile on my Macbook on Mozilla. 

I am a single member LLC so while I did do an operating agreement with another site (there was a trial period so I completed the form and then cancelled my membership, but may return in the future)...just for formality sake...I didn't feel it was absolutely necessary.

It was trial by fire and learn as you go until you strung enough deals together to the point where you knew the ins and outs. 

Through trial and error you should find the right wholesaler, and you and them will be prosperous in this business.

So if you care comparing pricing, I would use $150/mo as a minimum price tag for Buildium.They both offer free trials though, so give em both a shot and see which works best for you.
