I live on Long Island and are looking to get my feet wet this spring.

I lived in an 900 sq ft house. 

I live in Ca, this property includes a liquor license.  

I have always been more comfortable wearing my work boots than I ever have been in a suit.

I am a first time real estate investor looking the following property : https://www.redfin.com/OR/Forest-Grove/2418-Cedar-Cir-97116/...its a pretty large duplex in Forest Grove OR,  the trick is though, its on a lot zoned for a 4 plex so I am lookinginto house hacking, converting into a triplex, then living in one unit while renting out the remaining two unitsThe left garage has been converted to living space, with a living room, half bath, a laundry room with a sink and some counters/cupboards and a bedroom, it is a part of what was an existing 3bd unitIf I were to acquire the asset, I would first attempt to convert that space into its own unit The line items as I see (be in mind, I am totally new to this) would be to >put up dry wall where the door to the rest of the house is,>add a shower to the half bathroom >install a water heater in the adjacent 3bd unit> install a kitchen in the laundry room, (stove , oven , sink, counter space)>add a shower to the half bath Assuming I can convert it to a 3plex, I could at-least cash flow on my investment after I leave My plan would be to put minimum down payment of 3.5% (FHA loan) that way I can have a decent amount of capital free to do the renovationsThe only concern is when I crunch the numbers to get my ROI, I have no idea how much its going to cost to convert the additional living space to a third unitAny experienced investors here know how I can estimate this before I try to make an offer?

The refinance frees up the cash to live on or to purchase your next "flip" immediately. 

Sellers are still wanting "too much" as they typically think their deals should still be trading in the 4-5% cap rate range.While I won't pretend to have a crystal ball, I generally think: a) if you want to get a deal today, you are going to need to be more aggressive then you probably are comfortable with in your assumptions.  

"Adirondack Cove Subdivision shall be comprised of the following deed restrictions to keep the neighborhood a peaceful and harmonious place to live.

You could live in one of the units and use the other $250,000 to buy a multi-unit property, which you would then rent out to pay your living expenses.2.

I've lived here my whole life.
