Not impossible, but I would be happy to discuss in length for our market specifically - assuming you are talking about the foothills to our East.

Throw away the nails with the ash when you clean out your fireplace.If you are going to do another framing project you can cut down the studs to 14 1/2" lengths and have precut blocking for the next project or three.

There are towns here in Florida that have restrictions on this like minimum stay length and usually charge a business tax as well.

A "Check out instructions message" 1-2 days before they leave depending on length of stay.

And you bear the risk that they might destroy your renovations.There is no specific length of time required by tax law.

@Albert Bui @Carlos Valencia Agree with this - don't be fooled by the simple IO number - other factors such as (interest only vs. amortization schedule, amort schedule length, closing points or buydowns, prepayment, and more can have a huge effect!)

It has a few questions such as employment length, do you smoke?

Depending on length of tenancy, carpet is debatable...

Most don't require income verification meaning no tax returns, paystubs or p and l are required.As an example, a guarantor with a 760+ middle score, who is looking for a 250K loan amount on a single family property at 75% ltv, cash out, will get a rate of 4.5 to 4.75% depending on the length of the prepay. 

If the LLC buys an asset, that is where asset protection comes into play, when a LLC is transferred a property for no money transferred and its not arms length, that is pierced as easy as warm butter.
