Now the owner of the property has damages in the amount of $50k plus additional carrying cost that they may sue you for.

hello, If I am the owner and sell a property by owner financing it / carrying the note; can I still do a 1031 exchange? 

expenses fall into one of two buckets.Expenses that need to be pro-rated - These are expenses that is one amount and benefits both the main home and the ADUExpenses that are only applicable to the ADU - These are items such as repairs/supplies to the ADU.

I recently started carrying some notes and that is great passive income. 

Really quick......some think its a dishonest, illegal practice since it could be construed you are "hoodwinking" the seller since you aren't going to be the buyer AND the fact that since you are making a buck on the deal, you cheated the seller out of money that they could have earned......some wholesalers aren't upfront with what they are doing so people get pissed off......Legally, you need to be able to carry through on the deal in case you don't find somebody to sell your purchase rights to. 

If the deal can support it, you can have the owner carry a note in second position so you only have to come up with 5-10% down but it is unlikely a bank will allow for a lower down payment, unless it is a screeching good deal and they felt covered if you are buying at a significant discount.

An inexpensive parking pad option (asphalt and concrete are the standard methods) is to form a 20' x 20' square on each lot with landscaping timbers, metal edging or even railroad ties, and then filling that box in with crushed granite or some other type of rock.Replacing roads is one of the highest capital items in any park project, so make sure that your deal will support this cost.

30 Day notice and if you have it sent from a lawyers office it might carry an extra bit of weight that could get their attention as they clearly are not paying attention to you. 

The pump had failed multiple times due to folks flushing inappropriate items (wipes, qtips etc)We would annually pull the pump and service and clean it.

Would it be possible maybe sell the home owner finance the home with 20% down payment then just carry the note?
