He talks about obtaining private money.

If you own the balcony (check CCRs, I have a unit where I don't own my private balcony) then it is all part of the unit.As an owner, you're on the hook for the actions of your tenant.

Feel free to private message me with any additional questions.

This is a 3 story town home (detached) that shares a private sewage line with 7 other homes.

Hard money, private money, joint ventures, even lines of credit secured against existing assets—there’s a ton of capital out there looking for strong operators.

Many opt for other investing methods in their SDIRA like private lending, crypto, private equity...anything except collectibles and life insurance.Note that a Solo 401k is exempt from UBIT on leveraged real estate so if you have self employment activity and no full time employees save for you and your spouse you should consider the Solo K as an option. 

It's not difficult (shouldn't take long) to get flood insurance quotes (NFIP & private) if you work with a good agent.

Or just use private money. 

Another great option is the BRRRR method (Buy, Rehab, Rent, Refinance, Repeat), where you buy a fixer-upper, renovate it, rent it out, and refinance to pull your cash back for the next deal, and this is a good route because most private lenders can go higher LTV than on a rental loan! 

If you are tight on cash, then you want to use the lender that has the least up front charges to minimize your contribution.When I need to close fact I use private money.
