in hearing you the only thing that would concern me is how little the bed bugs have cost .. our experience with bed bugs is we have never paid less then $1k  to get a house properly treated and the only proper treatment legal right now in NC in heat treatment bc there are not sprays that work to permanently rid bed bugs.    

In 2013, my MIL was diagnosed with cancer, so we decided to buy, again sitting in the UK, in FL.  

Find a contractor who can do the wood replacement and get a couple of quotes if you need chemical treatment or tenting of the property.

The second is the treatment of expenses while it wasn't occupied at all; you state that it was "ready to rent" but then made some repairs and maintenance - those repairs and maintenance would definitely be expenses when occupied by a tenant, but might have to be added to the basis (if the IRS doesn't agree with your interpretation of "ready to rent").

It might be irrelevant anyway, since your LLC is most likely going to have the same tax treatment as an S Corp anyway....Ask a CPA.

I have a go fund me page, and I am also trying to help my friend with Stage 4 Breast Cancer, so I was hoping to maybe flipn a few homes, with their help, and get my brother involved so he could also have a income, since after 340 t years that let him go from his job, and he has 2 kids in college....I will be reading your comments and asking questions often.

His wife has cancer.

That would mean that at this time you do not qualify for Section 121 exclusion of your capital gains on the sale of the property, because you have not owned it and occupied it as your primary residence for two of the past five years.So, your question is can you move back into the property and occupy it for two years and qualify for the Section 121 exclusion of up to the maximum limit of either $250,000 for a single taxpayer or $500,000 for a married taxpayer.The answer is that you cannot.If you move into the property for two years and qualify for Section 121 treatment, you will have two years of "qualified use," and a number of years of "non-qualified use" that would be equal to the number of years you have owned the property minus the two years of "qualified use" as a primary residence.  

Tax treatment preference?

If it's a request to upgrade appliances or plaint or window treatments, politely tell them they viewed it and rented it so they clearly accepted it.
