I think you are smart to continue to do some research and familiarize yourself with the program. 

I'm not saying smart investments can't help make some things in life easier, but it doesn't have to happen as fast as it sounds like you want it to happen.    

I have tried using some, from time to time, and there are times that they device won't even work because there is not enough energy in the Harbor Freight battery. 

I recommend private landlords use TransUnion Smart Move.

It would not be a smart decision for anyone to loan 100%.

Start small, slow, and smart. 

Lastly, don't forget about other smart moves like using self-directed retirement accounts or 1031 exchanges to keep your tax bill in check.

A trust may offer some of the same benefits as an LLC, depending on your goals, and allowing you to claim the part of the house you live in as homesteaded tax.Make sure you have the right home insurance and consider an umbrella policy for extra protection.Certainly buying a house, using conventional financing with limited money down as a primary residence and renting out parts of the house to help pay the mortgage, is a smart financial move.

It literally takes 5-10 minutes to find a replacement, or you could call a local vendor, ask them to find the device for you, and pay what they charge, which is marked up to cover their research time.Keep in mind you can only charge depreciated value.

If your dead set on STR, then do it SMART.
