I would suggest looking into Hemlane, I have worked with the CEO personally and they have a great product that I recommend to all self managing landlords. 

But I can't recommend something I would not do as an investor myself, so here it goes:1.)

.- If you chose to set up your LLC as a pass-thru entity, then you will need to supply your SSN.FYI - to avoid getting nasty letters from the IRS about errors (which might cause us to be audited), we will ask for a copy of your EIN assignment letter or a copy of your SSN card to confirm those numbers.

I’d love to hear any tips or strategies that have worked well for you in real estate marketing, especially with PPC campaigns.For those who’ve done this successfully, are there specific keywords, ad placements, or campaign types that you recommend?

I work with a lot of househackers and they're typically on the 12 month cycle, rinse and repeat.While the proposition of acquiring an investment property outside of your market in a "landlord friendly" state may sound appealing, i would recommend you stay local for now and househack another couple of properties over the next few years until you've got some more time / experience under your belt.you would need a management company to cover your property that is outside of your market which would not only take 8-10% of your gross it would also leave you a bit vulnerable to a property management company that you A.)know nothing about and B.)you won't have the experience or cashflow or proximity to deal with any headaches that may arise.i would recommend staying local and househacking your way along for now and then maybe hire a local property management company initially to work with your current/local properties to get a taste of what to expect if and when you begin investing outside of your market.

Quote from @Esther Iroko: @Nathan Gesner please don’t have any attorney that you can recommend.

A good real estate accountant can save you thousands of dollars by leveraging entity selection and formation, tax deductions, cost segregations, bonus depreciation and tax planning.I recommend finding an accountant specializing in real estate taxation, business taxation, financial planning and tax planning.Consider working with your accountant remotely to expand your options.I would also recommend looking for an accountant willing to work with you throughout the year.

Most professionals will recommend a separate LLC for every $1 million in assets, but I don't think that's necessary.

So Supply and demand have really shifted quickly. 

I don't personally have an umbrella policy but if you do want to be extra safe, yes, I would recommend an LLC and umbrella policy together.
