What's your end goal —cash flow or long-term generation? 

I am currently looking to set up an LLC to list our 3 short term rentals under.  

Never had to do this ever before  There are two ways to do this, google and find a template online or get a realtor that can use some promulgated documents by TR.Per law, no-one can write you a legal document except for an attorney or the person providing the document will be infringing the law.In terms of the tenant leaving there is no point to pursue any legal way and for you to get possession, you create a termination notice and then in 30 days you can take possession.

Here's my situation:I own a duplex that is about 100 years old and my tenants pay for all of the utilities EXCEPT for city water (which comes out of my pocket each quarter).Both of these rental units could benefit from some plumbing updates throughout (e.g. - 1.28 gallon toilets, eco-friendly faucets, eco-friendly shower heads, etc.) as a way of helping this rental property consume significantly less water (enough to save me a few hundred bucks each year...

This will give you several benefits.

Saw a house with a For Sale by Owner sign in a yard with tall grass and after some drama, we have a house.We have dealt with long term rentals for over 15 years, but not aggressively ( keep them rented and do some improvements ).This "old house" needs, updated HVAC, new roof, new kitchen, some broken windows, upgraded electrical, water run off issues...I'm just starting to clear the house out with multiple dumpsters and starting to get quotes.  

If you flip a house with in a year and incur a tax rate, “ordinary income”then does all of your other income from your rentals “long term income”get taxed at the same rate as ordinary income?

These buyers benefitted from lower monthly payments and avoided the intense competition seen in subsequent years.As inflation picked up, partly due to increased government spending and monetary policies, interest rates began to rise sharply, reaching around 7.5% to 8% today.

.- Only allows Rate/Term but we could add a HELOC on top of it to access cash in this instance up to 95% CLTV.Long story short, there are ways but you'd have to get creative and be over 62. 

ButI'd really like to know what places you found that allow short-term rental along the beach?
