do they confirm that they know the property is transferred and you are the new owner.

Next, is there any legal way to personally finance the properties then transfer the property to the LLC's?

Many of these agents are not selling so they do the reports to get by and I can see where they have no clue about market conditions except what data they pull from the MLS.BPO's I haven't completed those in about maybe 6 years.

Numbers may vary slightly because of where the data may come from, regardless it tells the same story. 

@Detric MotonGive us some data. 

Once the published data catches-up it will be interesting to see if we are experiencing an uncharacteristic spike arising from the temporary relaxation of lending practices a decade ago.

No data to support your theory, particularly on SFR, if for no other reason than neighbors would never know a tenant was receiving Sec 8 subsidies, unless the landlord or tenant told them.  

The seller would be obligated to let you know what agreements and such are currently in place, and whether they would transfer in a sale.

The data field "BPO" in the market place is a catch all for real property value.  

Did some more research and I learned that:Carryover losses extend indefinitely until final sale (and can be transferred from property to property if a 1031 is used).
