Hello Ralph,Yes you can used a HELOC from another property as a down payment for a new one, then get traditional financing on the remaining 100K. 

we have a flag lot and constant deliveries every single day.. so far so good.. we are on a culdesac with only 3 houses ( built mine and the one in front) someone would have to follow one of the vans to snag ours as you cannot see them from the street and I have not had anyone pull up into my driveway as you would have to back out.

The gain just must be reinvested in a QOF within 180 days.

Quote from @Frank Chin: @Matthew SpiegelSome years back, I used to go to the local building or planning departments, and get the information from the local offices directly.

We have a tons of lots around here like the one you described, many of which can be bought for cheap and are not listed because there are just barely any buyers for such.

Other distractions include non income-producing activities - aka any distraction pulling you to do something other than speaking with and following up with people.How can I prepare myself?

Does price per square ft factor or is it just ARV.
