Renewing Türkiye's building stock, appraised the URAR way

US residential appraisal criteria (Form 1004 / UAD C1–C6 · Q1–Q6, three approaches, reconciliation) adapted to TBDY 2018, Law 6306 and DASK — then a construction-to-permanent workflow: underwriting, tokenized renewal bonds, inspector-gated draws, completion certificates. Collective imece production cuts cost ~35 % and shares the value-added with the public that built it.

QA NoScan 2452 covers a 1998 reinforced-concrete frame building in Antakya, Hatay — 6 storeys, 24 units, 2,400 m², now carrying a high structural risk score of 55.2 and a UAD condition rating of C4/Q4, reflecting visible distress and seismic vulnerability typical of pre-2000 Hatay stock. Three value approaches frame the case. Sales comparison anchors the as-is value at 53,767,000 TRY, based on comparable unrenovated units. The seismic-risk-adjusted figure of 43,390,000 applies a cost-to-cure/risk discount reflecting retrofit or rebuild likelihood and market caution toward high-risk buildings post-earthquake. The as-renewed (prospective) value of 90,000,000 TRY uses an income/cost-to-build approach assuming full reconstruction to current code, with energy performance moving E→B and accessibility rising from 22.5 to 92 — both value-additive under UAD guidance. The risk discount is driven mainly by the 55.2 structural score and C4/Q4 condition, which signal elevated collapse risk and reduced marketability absent intervention. Collective (imece) production cuts renewal cost to 46,618,000 TRY — a 35% saving versus individual contracting — and the resulting value uplift is shared: owners gain equity, while efficient collective delivery reduces public disaster-recovery burden, supporting a B/C of 1.0 and NPV of 28,191,000. Underwriting approves with conditions: loan 39,580,000 TRY, LTV 44%, DSCR 1.34, rate 7.5%. The owner's immediate task is clearing the Halkbank mortgage lien — releasing or subordinating it before any bond issuance.
