Renovate as Duplex or SFH

[Ruben Sanabria]

Found a duplex that I'm interested in employing the BRRRR method. However, if I rehab the duplex, there are no comps, thus the appraisal will likely not hold. The potential rents as a duplex are great.

If I rehab as a SFH, the comps are great, but the rents are not. There are many comps for a SFH as this is in a great location.

What do you all suggest? If there was only a way to appraise as a SFH, but keep/rehab as a duplex. Open to any advice/opinions
