Is HO6 Cheaper Than HO3?
Usually, since HO-6 only covers the unit interior, not the whole building the HOA's master policy insures.

Why your condo policy costs less than a house policy
An HO-6 is cheaper mainly because it isn't insuring a building. It covers what's inside your unit's walls, the drywall, flooring, cabinets, fixtures you've added, plus your belongings and liability. The HOA's master policy carries the real weight. It covers the roof, the structure, the exterior walls, and often the plumbing and wiring behind them. An HO-3 for a standalone house has to cover all of that itself, so it costs more to insure the same amount of risk. What narrows the gap is how much your HOA's master policy actually covers. Some master policies only cover bare walls, leaving you to insure more of the interior yourself, which raises your HO-6 premium. Your HOA's governing documents or master policy declarations page will tell you where that line falls.

A bare-walls master policy pushes more rebuilding cost onto your HO-6. Comparing quotes shows what that gap actually costs to cover, and whether your current limits match it.
What loss assessment covers, and what it doesn't
When the HOA has a loss and the master policy doesn't cover all of it, the association can bill every owner their share through a special assessment. A fire in the lobby, storm damage to the roof, a lawsuit from someone hurt in a common area. If the master policy limit falls short or the loss involves a deductible the HOA passes down, the bill shows up on your side.
Loss assessment coverage is a standard part of most HO-6 policies, and it pays your share of that bill up to its own limit. Insurers usually build in a small amount by default, often somewhere around a few thousand dollars. That default is often too low for what a real assessment runs. A structural repair or a liability settlement can produce an assessment of tens of thousands of dollars split across owners. Raising this limit costs little relative to what it covers. It's worth checking against what your HOA has assessed owners for in the past, if anything. Meeting minutes or a call to the HOA board can tell you that history.
Water from a neighbor's unit is a separate question, and it depends on where the water started and why. If a pipe bursts inside the unit above you, that owner's HO-6 liability coverage may pay for damage to your unit. That only applies if they're found responsible for negligence, like ignoring a known leak. If the pipe was old and failed on its own, no one may be at fault, and each owner's own policy covers their own damage. Your HO-6 covers the interior finishes and your belongings. The HOA's master policy may cover the pipe itself and the structure around it, depending on where responsibility for plumbing falls in the governing documents. These cases often involve more than one policy responding to pieces of the same loss. That's why many HO-6 policies also include water backup coverage as a separate add-on, since it's often excluded from base coverage entirely.
Townhomes complicate this further because ownership structure varies. Some townhome owners hold title to the land and the structure outright, with no HOA master policy at all. That setup calls for an HO-3 like a standalone house. Others belong to an HOA that insures shared walls, roofs, and common grounds, closer to the condo arrangement. What a particular townhome needs depends on the HOA's declaration, not on the fact that it's attached to a neighbor's unit.
How much dwelling coverage does a unit actually need
Setting the HO-6 dwelling limit, sometimes called coverage A, isn't guesswork if you start from the right number. It's not what the unit would sell for and not what you paid for it. It's the cost to rebuild the interior the master policy doesn't cover, from the drywall in if the master policy is bare-walls, or further out if it's not. Real estate value includes the land and the building shell, neither of which the owner rebuilds out of pocket. A unit that sells for a high price in a strong market might need a fairly modest HO-6 limit if the master policy carries most of the structure.
A few things push that number higher than owners expect. Renovations are the big one. A kitchen remodel, new flooring, built-in cabinets, upgraded bathroom fixtures, all of that is the owner's addition, and the master policy was never covering it since it didn't exist when the building was insured. If that work isn't added to the HO-6 limit, it isn't covered in a loss. The same goes for anything original to the unit that the master policy excludes, which the declarations page and the HOA's master policy summary together will show.
Getting the number right usually means working from two documents at once. The HOA's master policy declarations page shows what's already insured and where its coverage stops, whether that's bare walls, original specifications, or something in between. The unit owner's own records of what's been added since purchase fill in the rest. An agent or the insurer can help translate that gap into a dwelling limit, but the owner is the only one who knows what's been renovated and when.
Personal property and liability limits work more like a standalone house policy once the dwelling question is settled. Coverage for belongings should reflect what it would cost to replace them, not their worn present-day value, unless the policy is written on an actual cash value basis instead of replacement cost. Liability coverage matters more in a condo or townhome than it might seem, since a unit owner can be named in a lawsuit over an injury in their unit or damage that spreads to a neighbor's, separate from anything the HOA's policy addresses.
Before you compare quotes
Pull your HOA's master policy declarations page and your own renovation records. Match what the master policy already covers against your HO-6 dwelling limit and loss assessment limit, so neither leaves a gap the other was supposed to fill.
