Then you just choose how to go about acquiring those properties, and adjust as necessary.I am guessing you probably already thought of a lot of this, but hopefully, that was somewhat helpful.

My wife and I were able to use the equity in our first home to cover the 20% required for a conventional loan; will most likely be your best bet if your gf has the equity for it. 

., you bet you can.

I adjust my vision and look around and find hooks and chains on the wall and hooks on the ceiling along with one occupied by a swing.

Your best bet will be local facebook groups (search the city and use key words like: XYZ City in Washington/Arizona Real Estate Group or Real Estate Investors). 

@Milton Carrillo your best bet is going to be to go to the city and speak with someone in the Building Department or Planning Department. 

If the PM is listing through AirBNB/VRBO you'd still pay those fees on bookings through those sites.In fact, I would bet a lot of PM companies calculate gross revenue before those fees are taken out, so they're actually charging you their 15-30% management fee on the VRBO/Airbnb fees you're paying, effectively INCREASING the Airbnb/vrbo fees, not lowering them. 

Should I be patient and wait for a good four-plex to come on the market to house hack using FHA, should I use an adjustable rate in-house bank loan with 15% down to purchase a four-plex in a different area further from my job, should I save up more cash to purchase and rehab a BRRRR, or should I combine some of these options and use all my savings to invest in both a four-plex with a 15% down in-house bank loan while also purchasing a good four-plex with FHA when one comes up?

Your best bet is to talk to a few hard money lenders who could share with you how they do business, what your payback schedule would look like (often nothing until due or interest only), when the loan is due, and how much they would loan on a sample property.

Do I go back and adjust these amounts (restating my income statement) or do I just make an adjustment in November for the $1,000, basically debit property tax payable (reduce a liability) and credit WHAT?
