I have a 753 sq ft property that needs flooring, kitchen, and bathroom.

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?

Then i painted the whole house and refinished the kitchen cupboards.

If you can't see certain rooms, like the kitchen, just budget for a complete kitchen.

How important is the kitchen either in your own house or your rentals?  

This Mountain Modern condominium has high-end finishes in kitchen and bathrooms including heated floors and custom built-ins in the living room.

Remodeled Kitchen and Bathroom, updated AC Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

Hey Zane, totally can relate with you being from an expensive real estate market - I moved to Columbus a few years ago (from Portland, Oregon which was super expensive) to become a full time real estate investor, and ever since, I've completed quite a lot of BRRRRs, flips, and own a successful rental portfolio here in Columbus Ohio.

I added value by redesigning the kitchen and opened up the space by vaulting the ceiling, relocating the stairs, and knocking down some walls.
