If the property has equity, be prepared to sell before FC or have access to funds to payoff the loan.

My husband and is purchased our first house hack almost two years ago and are preparing to put an offer on a 4plex.

Mentally prepare yourself to spend another 10 to 20% repairing stuff that wasn't obvious at the beginning. 

I don't have much saved up (6k) and I have good credit (700+) with minimal/manageable debt.

In Northern Indiana (Nisource), it used to be 20+ years ago (and I assume its still the case)  you would have to put a deposit down to cover the gas and electric distribution services, and you could get some credit back based on houses going into service with some assumed usage patterns.City run utilities and REMC's would have drastically different practices. 

If you ask for a change be prepared to reimburse the bank the legal costs to research your question.  

I'm curious as to how an 18-year-old managed to pass your screening since they likely have zero credit and zero Landlord reference.

My credit score is 808.

My total bill last month was $2800 which put's me on track thus far for over 33k per year not including tax returns.I should disclose that I have another business that keeps me traveling pretty much half the year.Our Real Estate business operation looks like this:Property manager handles tenants and collects rents, he deposits all rents into our accounts and coordinates the rent roll with bookkeeping, they cut him a check for his gross collected rent management fee, bank statements are automatically sent to CPA's office for them to reconcile against business credit card statements, they also handle 95% of day to day financial operations from there to include paying contractors, setting up utilities, paying company bills ,bank deposits etc. for 4 and now 5 entities with the short term rental llc.We have a initial goal of 100 doors so I it's pretty easy to see this cost jumping significanly in the not so distant future.

I'm currently in the process of fixing up my primary residence in preparation for an appraisal to use for obtaining a HELOC.
