@Landon Sheveland People do fix and flips while living into the property to classify the property as primary residence and not pay any capital gain taxes. if that is your intention, don't use LLC to establish this as your LLC.If your goal is different compared to what I said above, you can use LLC.

It may end up being a loss or small gain, but most of them won't end up being a fire sale. 

Major cities where STRs have only began rising up and gaining public spotlight with the rise of AirBNB are more likely to have more shifting and less stable regulatory environments since those areas are still in the process of trying to find the balance for STRs within their markets. 

Also we run cement to the rear of the man door so garbage cans can go there and are not in the dirt or have to be in the garage taking up valuable space.

Quote from @Femi Alakija: As a newbie, I plan to gain a deep understanding of real estate fundamentals, including financing, property evaluation, and market trends. 

Talk to an accountant prior to doing the cost segregation study.You want to discuss whether it will be beneficial or not.In general real estate is considered passive which means that it can't be used to offset other forms of income such as wages, interest, dividends, capital gains, etc.However, there are some exceptions where the real estate loss can offset these types of income.best of luck.

Also we have two great BP meetups per month here that you might find really valuable.

I don’t know your exact situation, but I expect principal paydown and appreciation to cover the $200 and still give you a nice gain.

It just feels like I’ve been making a lot of short term sacrifices for long term gains and I have to be really diligent with money management. or I could also just try to borrow money for the renovation, and pay off the line of credit over time, but I feel like that really would limit me and if the stock market(my collateral) went down I could also see some trouble. 

Solo 401(k)s are not subject to UDFI (Unrelated Debt-Financed Income) on the capital gains from selling a debt-financed property, per IRS rules.b.
