The 1031 must be a sale of investment property followed by the purchase of investment property. 

Yes, the more units you go up, generally the less players in the game so there is some advantage in purchase competition as you go up, but also more management scale and cap ex for someone who is new.3.

I'm looking to purchase a single family home as an investment property (buy and hold strategy).

Recently, I've decided to do a cost segregation study on a new $490K property that I purchased this year. 

You just divide the monthly rent by the purchase price.

Quote from @Fernando NA: Hello everyone,I’m considering purchasing a piece of land near Divide, CO, to build a small off-grid log cabin and list it on Airbnb or similar platforms.For those of you who live in the area or have experience with this, I have a few questions:>Is it possible to list such a property on Airbnb given the local regulations?

I like small units (they don't trip breakers) and they are cheap.

Example - borrower uses loan to purchase a home in a B or C grade neighborhood for 380k, spends 50k rehabbing primary home, uses 200k to put an ADU in the back, appraisal comes back at 925k. 

Not a one-time purchase.

My experience has been that purchase transactions where the buyer has no or little skin on the game have a default rate many times that of buyers who place a significant down payment into the deal.
