Stop guessing.
Own the range.
Roilyze pulls live comps on the house you are about to bid on and gives you a min, base, and max — so you know the floor before you write the offer.
Three analyses a month on the house. No card required.

Sample for a 3-bed. Your report uses live comps for the address you enter.
2148 Magnolia Ave · Charlotte · illustrative
Same address. Two strategies.
Run STR and LTR on the house, not the zip code
Short-term
Nearby STR comps
Revenue, occupancy, and ADR from AirROI listings matched on beds, baths, and location.
Long-term
RentCast rent band
A rent range and value estimate for the same property if you lease it conventionally.
How it works
Address in. Range out.
01
Enter the deal
Address, beds, baths, and the price you would actually pay.
02
Pull live comps
AirROI for nearby STR performance. RentCast for long-term rent.
03
Read the range
P25 / P50 / P75, cash-on-cash at 25% down, and a 0–100 deal score.
Why existing tools fail
A single number is a guess wearing a suit
AirDNA
One revenue figure with no range. One bad comp can move you 30%.
Rabbu
Market averages that ignore this property's beds, baths, and block.
BiggerPockets
You type the rent. You type occupancy. Garbage in, garbage out.
What you get
Enough to size the offer
STR comparables

LTR rent estimate

Cash-on-cash

Deal score
0–100 from GRM and cash-on-cash. A ranking aid, not a buy signal.
Confidence ranges
P25–P75 from the comps so you see the downside, not just the median.
