The building is the easy part. The financing runs on rules nobody explains until you are already committed.
The financing works differently from anything you have done residentially, the diligence costs real money before you know whether the deal is approved, and the two things that most often catch a first buyer are the size of the equity required and the length of the subject removal period they agreed to.

First, get a realistic sizing. Before you write anything, find out roughly what the building supports and what you would have to put in. The commercial mortgage calculator gets you close on your own, and a deal review gets you a broker's read with no credit check and no cost.
Then write, with a subject removal period that fits. Not the one that makes your offer look competitive. The one that matches how long a commercial mortgage actually takes. This is the cheapest decision on the whole file and the most expensive one to get wrong.
Then order the reports, once the deal is firm enough to justify the spend. Reports get ordered when there is a lender and a structure worth spending against. Ordering early feels productive and is usually just money spent before you knew whether the deal was real.
A commercial appraisal from the lender's approved panel. An environmental report on most files, and on some property types a Phase II after it. Sometimes a building condition assessment. Legal on your side and the lender's legal on theirs, which you also pay for. And your own time, which is not free either.
We do not publish figures for any of it, because the numbers move with the property, the complexity of the assignment and how busy the panel is, and a made up range would be worse than no range. What is certain is that these costs are real, they land before you have an approval, and they are not refundable if the deal dies.
That is the entire argument for getting a read before you spend. Send us the property and the numbers and we will tell you whether it is financeable and roughly what it costs, at no charge, before you commit a dollar to reports.
A subject removal period set to a residential timeline. Two weeks is a normal residential condition period and an impossible commercial one. The appraisal alone can take longer than that to order and deliver. When the clock runs out you are choosing between removing subjects without financing in place and asking the seller for an extension you have no leverage to demand.
An equity assumption borrowed from residential leverage. Commercial equity requirements are a different order of magnitude, and they vary by asset type. Read the down payment page before you set your budget, not after your offer is accepted. A buyer who planned on residential leverage discovers the gap at the worst possible point in the deal.
Lenders do look at experience. On a complex asset, a repositioning play or anything with a management burden, a borrower who has done it before is a materially easier file, and a first timer will feel that in the questions and sometimes in the terms.
But inexperience is a factor, not a disqualification. A first time commercial borrower with a strong property, real equity and a clean file is financeable, and that describes most first purchases. Where it does weigh, it can be offset: a partner with a track record, a professional property manager, a stronger covenant on the lease, or simply more equity in the deal.
What does not help is arriving unprepared. The fastest way to look like a safe first time borrower is to hand over a complete package. The deal submission checklist is the list.
Send it before you write. We will tell you what it supports, what you need to put in and how long to give yourself.
