Legal Question in Real Estate Law in Colorado

Sean,

Since you have expertise in this area, so long as you are charging a reasonable market rate, there is no reason you cannot do the work. It does, of course, provide ammo to a disgruntled tenant to argue about over-billing, but the risk may be worth it to you.

Just keep careful track of the hours and work done so that you can defend the billing if you ever need to. You might even get a couple bids on one property in each area where you own property so that you have documentation of what you would have been charged if you hired a third party and you can then more easily justify similar rates as market rate.

If you do this type of work for others, you could create an LLC for your property repair business and then bill yourself from the LLC for the work done on your rental properties and you can then provide a copy of the bill to the tenant.

The most important recommendation I make to landlords is to put each property in a separate LLC if you have not done so, so your liability as to each property is limited to your equity in that single property and limit the chances that your other properties/assets could be reached. Hope this helps.
