I recommend becoming familiar with the steps involved with a closing in your state, that will help you feel more comfortable with what to do and what services to engage.

I define a good tenant as someone who:Has stable employment in a market segment that is very likely to be stable or improve over timeHas a credit history with which you can evaluate the likelihood that they will performPays all the rent on scheduleTakes care of the propertyDoes not cause problems with neighborsDoes not engage in illegal activities while on the propertyStays for many yearsProperty SelectionOnce you select a good tenant pool, you target them through the properties you purchase.

I want this professional community to engage in professional dialogue that informs my and everyone’s ability to become more successful investors.

People who were already planning to buy are mostly still engaged in the process and haven't dropped out.

Karma is a cool thing, it has a way of finding the right people down the line.It sounds like you’re upset at the sellers in the quoted post and another above where you state that sellers are engaged in extortion.

We need to focus on increasing the number of positive interactions we have and reducing our negative interactions.We need to engage each other with more smiles, kind words, encouragement, gratitude, meaningful conversations, honest dialogues, and sincere positive interactions.

Have you engaged with wholesalers in the area you are looking at? 

And, know this:  you didn't engage the plumber. 

Is is because the current owner is not engaged?

@Nagesh PulipatiJust to clarify: UBIT stands for Unrelated Business Income Tax, this is a tax that is assessed when any tax-exempt organization (this includes both self-directed IRA and Solo 401k) engages in business activity and receives business or earned income from such activity.
