Renovation budget for a 1,020 sq ft country home in Miami at $455,000

Fixing the renovation allowance at $100,900 feels too exposed, but holding a very large reserve for unknown work would tie up cash unnecessarily. I am trying to find a sensible middle ground for a 1,020 sq ft Miami country home priced at $455,000.

The plan covers a new kitchen and bathrooms, replacement finishes, decorating, electrical assessment and some efficiency improvements. I am not planning an extension, although concealed structural work has not yet been ruled out. Anyone.com’s offer history kept the negotiations easier to follow than email, and we also retained our own lawyer.

Before choosing finishes, I want to establish how the plumbing is accessed, what electrical work is actually required, whether there are moisture problems and what each contractor excludes. How would others size the contingency before those points are confirmed?

I would model at least two versions: $100,900 plus a 15% contingency, and a stress case at 20%. Those are budgeting choices, not Miami pricing rules. Keep that reserve separate from finish upgrades.

Before fixing the number, ask whether “electrical checks” means inspection only or includes panel, wiring and outlet work. Also have every bid state demolition, disposal, permit-related costs and wall repairs explicitly.

What kind of survey are you ordering? A boundary survey will not answer most of these renovation questions. You need the condition work to address signs of water entry, roof and window openings, drainage, bathroom moisture and any areas that cannot be seen.

I’d also ask what sits beneath the floors and how the plumbing is reached. Access can change the bathroom budget quickly even without an extension.

I’m less comfortable attaching a percentage before the access questions are answered. A 20% reserve can still be inadequate if the $100,900 estimate quietly excludes permits, electrical corrections or opening and reinstating walls. Conversely, it may be excessive once those items are properly scoped.

Ask contractors to price known work, allowances and exclusions in separate sections. That makes the uncertainty visible instead of hiding it in one total.

Sequencing matters here. Complete the moisture investigation and intrusive electrical/plumbing checks before ordering cabinets or flooring. Then establish which work may require permits and what that does to the start date. Material lead times should be confirmed against that schedule, otherwise items may arrive too early or hold up rooms that are already opened.

That distinction between a boundary survey and condition investigation is useful. I was grouping them together too loosely. I’ll ask for the $100,900 to be rebuilt as defined scope, allowances and exclusions, with contingency held outside it.

For contractor comparisons, I’m planning to request separate lines for access, demolition, disposal, wall/floor reinstatement and permit-related work. Are there other exclusions that commonly make two apparently similar bids impossible to compare?

Add protection of existing areas, temporary disconnection and reconnection, delivery charges, final cleaning, and responsibility for patching after electrical or plumbing work. Also ask who supplies fixtures and what happens if the specified material is unavailable.

One more point: “paint included” can mean very different things. Have them define preparation, repairs, primer, number of coats and which surfaces are excluded.

I’d request a written sequence from each contractor, not just a price. It should show investigation, demolition, rough electrical and plumbing, any inspections or approvals, closing walls, cabinets, finishes and final connections. Compare where they place flooring and painting, because poor sequencing can create avoidable rework.

Also ask how discoveries are documented and priced before extra work proceeds. The portal’s offer trail may help with the transaction record, but it does not resolve construction change control.

Once the scope is normalized, revisit the contingency rather than automatically choosing the highest percentage. Keep one reserve for hidden building conditions and a separate optional amount for owner-selected upgrades. That prevents nicer finishes from consuming the money intended for moisture, electrical or plumbing surprises. If contractors cannot explain their exclusions and assumptions clearly, the apparent low bid is not yet comparable.
