Government is understaffed and tend to go after only the highest profile offenders.  

Focus on absentee owners and start with the ones who live the farthest away and only own one property in the area since they have the least use for the property.You can also drive for dollars, looking for anomalies of disrepair and then look them up in the tax records and use a site like Spokeo to do cheap skip tracing.

Quote from @Fred Scott: Sunrise Capital Investors - Mobile Home Park Investment FundI've seen a few posts about them here but none of them actually talks about what the actual annual returns have been.They are advertising heavily for passive tax deductions which is fine but what are the actual returns over a period of (say) five or ten years?

After that, I changed PMs' and a year later, still not sure if I'm safe from "cash grabs." 

@Rebecca GonaBigger Pockets is a great place to find a tax accountant that specializes in short-term rentals. 

To avoid Prohibited Transactions, SDIRA investments really need to be passive.Oh, I'll also mention that SDIRAs are subject to UBIT tax.  

Not only were tax shelters stripped of their tax deferral capabilities, but they were stripped of it RETROACTIVE, allowing the IRS to recalculate tax shelter investors income going back 7 years.  

Cash flow is definitely the biggest challenge; both in terms of finding properties to buy that cash flow with a loan on them and just company wide given interest rates and labor/material is up and, at least where I'm at in Jackson County, MO, taxes are way up too. 

If you live there 2 years or more before selling you will be exempt from tax on the 1st $250k in profit which is a nice bonus. 

You will want to fully understand the tax reporting burden you will face.
