Using RV as primary residence while renovating investment homes

[Ryan Best]

I was wondering if this makes investment/tax sense and if anyone has done something similar:

1. Buy an RV as a primary residence (I've checked IRS/State law and can do this in Arizona)
2. Buy and renovate an investment home while living in the the RV (versus renting an apartment)
3. Selling the investment home and then repeating #2

Due to the Covid pandemic, I am out of work and unable to qualify for a mortgage but have a lot of equity in my current primary residence home which I would sell to do the above. Note 90% of my equity is tied up in my current home which I paid cash for.

Until this year, I was doing the "buying a property, fixing it up and selling it after two years," to avoid short-term capital gains. I've done quite well financially buying/selling 8 homes over 16 years or so. I now want to start doing investment renovations and escalating the process.

Does this make financial sense to anyone, and has anyone else gone down this path?
