The benefits come in two different ways:- You will get to deduct the interest at the new activity level.

It doesn't pay tons, but is honest work and the pay is a little better than most other entry level manual labor, and I can work as much and whenever/wherever I want.Also, I don't work with just one app, but quite a few of them(Instacart, Doordash, Grubhub, Uber, Amazon Flex...) and my income is fairly inconsistent in each one of them, but at the end of the day, I usually get pretty much the same pay every month(4.5-5.5k).I decided that in the near future I would like to get a small multifamily and househack to get started in the RE investing world. 

@Timothy Burnes Don't do it. 10-20k in equity is not worth all those issues.Bed bugs are a significant defect that can take either $5000 and tenting the whole building for heat treatment, which requires vacating the tenants or getting them hotel rooms for a few nights, or a sustained program of prevention with bed risers, leg traps, sealed mattress bags, and the tenants need to keep it up for.. get ready for it.. 6 months, which is how long they can live without a meal.Sewage in the basement could be a big issue if you have a sewer backup problem.The sinking toilet sounds like it needs immediate attention, but at least that's a straightforward repair.The other issues are what I would consider "normal" as in, you could fix them but don't need to in order to make the place liveable.Based on the bed bugs alone I would avoid... if you are comfortable with this level of rehab you should be getting a way better deal. 

@Mike DymskiWhat Mike said.Go buy an entry level property.

The additional 2 units will be basement level units.

Both of these are Masters level clinical positions and can NEVER prescribe.

He is also shopping for sub contractors for too long and leaves total only one or two of his low level workers un-supervised with no foreman 80% of the time.

Zillow's Zestimate applies market level pricing to a single home.

"D" level property is a ton of work and limited equity appreciation.  

We’ll see if I can get more insight but I want to complete the work to start generating some income …it would complete to top half of the split level so We can start house hacking the in-law down stairs…again thanks everyone i really helps out
