For investments that are relatively static and singular in nature - shares of a private placement for example - the services of a self-directed IRA custodian can be sufficient. 

Example a unit sold for $300k cash, and next day was on rental market for $1700, within the week it had someone moving in there, and this is arguably the nicest area in Vegas.Rents have literally not moved.

For example, even for the home you already bought, you should have looked for a bargain, which might have meant that even in this one year, you would have achieved 20% equity!

You’re example is correct.

Can you give an example?

With rehab project costs, for example, at a minimum you need to know how to do a walk-through on a property with a checklist, and then estimate construction costs so that you can intelligently vet contractor bids. 

Example:- if this is an Emergency hang up and dial 911- If you are calling about a mechanical system not working such as A/C, Dishwasher, Plumbing, and etc.

So loans that would be Fannie Mae backed for example.

Dave H  For example:

I've always viewed vacant units, and those units were always freshly cleaned and painted and appliances clean or new with no lingering odors.
