The simplest way to get clarity on this is to have a great relationship with your primary home lender -- if you happen to have this then the best way to know would be to ask them candidly for advice.The most prudent move would be to push the second property's loan processing back just enough for the first property to close before the formal paperwork starts flowing on the second. 

I have the simplest finances on earth to keep up with compared to anyone who falls outside of that category.

Would certainly be the simplest, cleanest, and least risky avenue.

Decide if it’s your investment with the bonus of helping your daughter or an investment IN your daughter.If the later, simplest route is to have her take out the loan with you as a co-signer.

Simplest way to figure all of this out is to become an Agent, as an Agent you would have access to MLS data

Simplest path of course is to bank your cashflow and save for your next purchase organically.

Simplest is to just buy a good WiFi repeater/extender and put it in somewhere central in her house, so long as it can access your signal.

However, I don't think MLS has operating data beyond the simplest stuff - Then you're trusting the broker did it right, which is maybe 25% of the time when I look at residential broker listings.

There are so many different ways to get started in real estate investing, so I'll focus on the simplest paths here.
