It did not cost me $0.01.  

I decided to look into an official duplex or triplex putting 150K down that has value add with renovations and potential unit add but it wont have as much equity because it will be an on market deal. 

If I were to purchase an Airstream to use as lodging while I travel across the US to my rental properties, make repairs, and perform lease turnovers, would I be able to not only deduct fuel and campground costs but also depreciate the purchase price across 5 years? 

Yes we avoid custom work to help keep cost down. 

Quote from @Hanna Brown: @Jay Hinrichs If the bidder at the auction pays cash for keys to get the homeowner out, does the person redeeming from the owner position (exercising rights of redemption w/in 180 days) have to reimburse them for those costs they paid to get the homeowner out? 

I get it...I get emotional with properties and buy into the sunk cost fallacy too.

Not sure what your monthly cost is, but every vacant month it costs a lot trying to make that up. 

I would also suggest finding a 100% LTC (loan to cost) lender that will fund all of your rehab and all of your purchase.

You are adding costs and complications for no benefit at all.

However, in California, each LLC incurs an $800 annual franchise tax plus gross receipts fees if revenue exceeds $250,000, and property insurance may cost more.
