Two notes:1) The solar company may give you the best interest rate.2) If the power goes out, you still don’t have power if you have solar. 

What type of real estate investing are you interested in pursuing? 

Ensure the property appraises at its updated post-renovation value to maximize the equity you can pull out.A refinance isn’t a taxable event, but transferring ownership to your LLC may affect depreciation or future capital gains.

Quote from @Devin James: True, but it's foolish to invest without a basic understanding of how to purchase and manage the investment.

If you qualify, you can use passive losses, like those from depreciation, to offset your active income.

If it is that, then just replace the old one with a new one you should be good to go. 

You need to research/know the rules, laws and regulations (including HOA if applicable), like you'd do in any US city.

U have to vette folks to make sure they take care of it and just dont sell it .. :)  So with what you have raised and if you want to continue raising money you could follow the same path I did..

And that will be hard in short amount of time.Hope that makes more sense...but certainly feel free to just call me if you want to talk anything through.  

As @Nicholas L. said, it sounds like you are doing a BRRRR.
