Are rest of utilities separately metered? 

Can I utilize the business bank account or would it be easier to have the funds separated personally since the income is technically not under the LLC?

However, if the duplex is “two separate 1/2 duplexes” each on a separate parcel/tax ID number, then no you can’t buy both with fha, period.  

Purchase price: $30,000 Cash invested: $10,000 Sale price: $60,000 The house was an old church parsonage, the church was purchased separately and the house relisted.

@Dalton Chmelik No offence but it sounds like your wife is letting emotion control the investment journey.

I admit part of wanting to keep the home is emotional, but I also believe that it would be a good investment property and maybe the transition will be easier since I do own it already?

I also like one with a separate guest network so I can keep my smart home devices segregated.

Expensesget taxes from county. look at current valuation and you should have a good guess at how much it will go up based on purchase price.Find out what expenses are paid by LLVerify which utilities are separately metered; get average winter/summer monthly costs from utility company for any 'house' accountsGet quote per door from your insurance agentGet a quote from your landscaper (find out what they pay)Get a dumpster quote if you don't have city trash binsFind out if there is a parking lot sewer feeFind out rental registration requirements and costs (can be both county and muni)Income:Get the rent roll, In the contract require that you get estoppels signed by tenants and current owner saying amount of current rent, security deposit held, past due balances, and spelling out any promises for additional work/upgrades (there shouldn't be any). 

There is nothing wrong with continuing the collect the fee and holding it in a separate account while the tenants decides what they want to do.

If that does not work for you we can get together separately and then see what we can schedule.Just let me know.Phil
