Confirm with the solar company if the loan is transferable and review terms carefully—it’s a potential hurdle with lenders or resale.A DSCR (Debt Service Coverage Ratio) loan might be an option since you’re focused on rental income.

Some gurus tell practicioners of sub-to to hide transaction from the lender by saying the lender doesn't care as long as the payments are being made.

I also agree with No. 2, and I've seen some of my STR clients welcomed by their neighbors after taking over a ramshackle place that wasn't cared for.

You can certainly own multiple assets in the same LLC, but I would be careful about operating a business and owning other real estate or investments in that LLC.

You need to be careful around the risks of sudden price changes, market stoppages and watch for transaction fees.

Rehab Loans do not generally care about your DTI or your income.

They don't care about Yelp or the internet.

However, with the rates and conditions of any triplexes and fourplexes we could find (we did find one, but it's in the Pendleton Heights suburb of KCMO, so we were worried about it being too dangerous of an area), we were wondering if it's worth it to buy a duplex and rent out the other half to help pay the mortgage, or if it's more worthwhile to rent an apartment and try to save up to buy a residential or commercial MFH later?

The only thing about it is that the property hasn’t been very well taken care of, so we know there’s a lot of work to do to fix it.

Quote from @Brandon Weis: We have historically had in our leases that renter's insurance is required, but we had been lax on enforcing it because owners didn't really care and not all tenants had it.
