I have dabbled in real estate, but never heard of brrrr before now, and transparently never did much research outside of knowing that property ownership was a way to reduce my taxable income. 

It's just old mom and pop owners, many do not even list the rentals online. 

There are also many online calculators you can use if you do a search for them.

When it comes to analyzing properties, I’ve developed a specific checklist to make sure the home fits both resident needs and operational goals:Square Footage: Ideally, at least 2,000 sq. ft. to ensure enough living space for residents and staff.No Stairs or Pools: It reduces liability and keeps the home accessible for everyone (this is just my preference).Corner Lots: I love corner lots because they often provide extra parking and outdoor space—both of which are critical for families and visitors.

@Mordechai ChaimovitzGreat points made above along with what @Daniel C. said referencing @Tom Shallcross's post on another thread.The context and variables for each individual investor will vary but many people are comfortable with getting a 2-4 unit that will reduce their out of pocket expense compared to their previous rent with the intent to do rehab and raise rents over time.

Investing in multifamily properties offers steady cash flow, diversification, as multiple tenants reduce vacancy risks and provide consistent income.

No.But you do see their website online, right?

My question is, do I just use the heavily reduced price I was able to purchase it for since it was vacant, and then the material cost of what I renovated plus what things I did contract out, even though that basis would be way under what the other renovated houses that sold near me per SF sold at, or are you able to use similar comps to determine the depreciation basis?

Especially as it relates to being able to rollover IRAs and old 401k money into a Solo401k.Self employment allows you to contribute large amounts to Solo401k to reduce FICA taxes.

G'Day Alejandro,As a few have already mentioned, take a peak at Toledo also.In my opinion lower potential for long term appreciation but solid/"boring" cashflow.I prefer my portfolio to be "boring" but cashflowing lolLow entry points (Sub $100,000), high rents (Above the 1% rule).Blue collar working class decent folks that will stay and pay.Depending on the area but no derelict homes, yards well kept, cars with wheels and all tenants are employed.Plus, all are sophisticated enough to pay rent online so property management doesn't have to collect rents with bullet proof vests and shot guns lolI'm bias toward Toledo but it's worth considering.Wishing you much success
