Just make sure you are comfortable with the coverage amount.Or...Go to the MO website, fill out the appropriate forms to register your LLC, pick a local registered agent, and pay the fee. 

Your agent fees are far too low.

So if rent is late you get the late fee.

My question is this, how do I pay for all the due diligence ie the attorneys fees, survey, sewage tank inspections, etc.

Greg:    First, do not get discouraged by anyone, someone else is doing it so you can, not going to be easy.If not done already I suggest to look into this:Enforce that PM uses a great website for rental screening, ones with a background check and choose the best tenants possible.Review you leases to close any pitfalls and enforce the lease to the T.Keep the units in good shape and keep extra cash reserves ( fixing + trip expenses )Tiger than normal lookup on the PM ( have second PM line up ), vacancies, unit showing costs, repairs, fees, etc,  require a once a week normal operations report and a once a month full operations report.Family, friend on virtual assistant that regularly drive by the property and reports to you, or if cash flow allows and deem beneficial you can install security cameras and remote view activity on the property, nowadays there are lots of options.Check if feasible to get a home warranty plan for the units so some pain issues are self-managed by the tenant via a phone call to the warranting companyIn which city/state is the property? 

I haven't heard of one for $40 on a monthly fee.

It took an additional 4 months to close and the seller ended up spending $25,000 in legal fees to clear the title.I'd get the advice of a real estate attorney. 

I have to pay a monthly fee even if I don't do any tenant screening, but the platform also allows me to collect rent online and I don't believe they actually hold the money, unlike some other companies that have held, (and lost!)

UPDATE.I got an unsecured personal loan with a very high interest rate(18%) and paid over $1000 in fees.

The residents we put into our properties pays our escrow company all the mortgage and all our monthly fees, including the monthly profit to the seller and our monthly profit check.
