You have to try to estimate MTR income in your area + take into account the costs associated with MTR setup.

Kyle, south of Austin, ranked No. 2 with a 9% increase to 62,548 people, up from its third-spot ranking last year, while Leander, northwest of Austin, saw a 7.6% boost in population to 80,067 people, according to the data.In the new data set, Austin's population is pegged at 979,882 in 2023 — up 0.5% from the year prior — dropping it from the 10th to the 11th most populous city in the country behind Jacksonville, Florida, which has an estimated population of 985,843.Still, the Austin metro isn't stagnating.

That said I like to be able to run year end reports with an estimation of tax liability so I can provide financial statement information to investors/etc.

In 2025, the population is estimated at 58,518,843, marking a 0.3% decrease from 2024.

The rental market has softened in SF and that’s why the NOI estimate is less if I were to just market it for annual leases.

Quote from @Mike Sfera: for a duplex, is the BP rent estimate for per unit of combined?

. - Rents are also a function of supply - 2024 saw the most new construction of multifamily units in American history (nearly 575,000 estimated 2024 deliveries of new multifamily inventory), and 2025, while not a record setting year, will see deliveries top 500,000 again - a huge supply increase. 

People all of the time, "over estimate" the opportunity and "underestimate" the cost and challenges in doing a profitable flip.

If it’s a good enough deal you may not require a full 100% reduction by the amount of the estimate.

Just make sure to research your local rental market and get comfortable estimating rehab costs.It’s a smart plan, and you’re off to a great start.
