My parents have seller financed a free and clear property they operated as a fine dining restaurant in late 1990s, then transferred as a neighborhood bar.

Why would a realtor work with a customer for free.

I have had excellent luck with your local NextDoor neighbor marketplace and on FB Marketplace- better luck on Next door (www.nextdoor.com)- it's free to sign up and you can copy/paste from one site to the other and just add pics to each that you have taken and saved.

Feel free to reach out further if you want to talk more about the Pittsburgh market.

Regarding which one to use, it depends on what your priorities are when it comes to features.

Specifically, I have come across a single-family home featuring three bedrooms and one full bath, which is shared among all three bedrooms.

You absolutely do not need a team to set your pricing, there are lots of free automation tools out there.

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 you would need to use a clustering algo with features like average time properties on the market, prices of homes (indicating supply and demand, etc.) but even then you'd need to vindicate your inclusion of a feature and how you know a cluster class is really Class A vs.
