Is it converting to a condo? If so, then the current tenants are the best bet. Help them find the right financing.

I'd target all and the rest of the world. Not sure why you're limiting the target group.

If 1, 2, and 3 are my ONLY options then the 'Choose your neighbor' would be my preference. #1.

However, price point is a crucial factor in such decisions.

neighbors....if people love it there they have told others

3. They may be ready to buy. . .

Of the three options, you list I would speak with the tenants in the complex.

They already pay to live there so why not pay to live there. BUT, then again, onsite owners would probably like the opportunity to handpick their new neighbors

In some tight knit communities, number one is all you need!

From your choices, #1. Although I would actually market it to everyone without putting people into any type of group.

Why would you limit the target to these. I would send out a letter/postcard to all of them to let them know the home is on the market and do some other farming/marking as well. Invite the neighbors to an open house?

On site owners.

I am stumped as to why I would only target one buyer group.

Initial action would be to target those tenants with a full financial breakdown. They've always been my go to group Thomas and provided the most success over the years.

on-site owners.... they already manage one and they have familiarity with the complex .... 

Depends I'd need more info about the specific situation. Popular neighbor hood - check. Quick sales - check. Quickest buyer?  Current tennants who love the condo complex. And there could very well be landlords just waiting to scoop up another condo.

The only people who buy condos in my market are very senior Seniors!  Strange but true.

owners that would send the info to their friends.

I would not limit the efforts to specific segments of the market.

Thomas,

I agree with Nina Hollander 

With just the information you posted, I'd say off-site landlords. They are most likely to buy.

1) Owners already have a place and unless they want to change to a condo that suits them better, then the value would be in them letting their friends know a condo is for sale.

2) Landlords - This sort of depends on why they're landlords. If it is because they can't sell their place then not a lot of help. If they're investors, then they're likely to want to buy more and may have cash to pay.

3) Tenants - There may be a variety of reasons they're renting and it is iffy if they can or can't qualify for a loan.

Price it right and get it out there with good photos, staged and easy to show and be targeted by ready, willing and able buyers from all corners.

Target them all and send out Just Listed postcards to tenants and property owners!

Thomas J. Nelson, Realtor, ePRO, CRS, RCS-D does your county assessor's website list current ownership? If so I'd see who already owns multiple units and I'd target them.

Offisites inquiries will get you the juice.

I am with Nina Hollander 

Why limit the target market?  Cast a wide and deep net and market the holy heavens out of the listing. 

I suspect I am missing key information here. 

Assuming it's not a "all units are identical" situation.  If it's one of the move-up models or the largest model, maybe on-site owners would be interested.  Smaller entry-level unit, probably not.

Landlords: Any of the unit sizes would be good for them, but how big is the pool of landlords?

Tenants: They may be interested in buying it, or buying in general.  Only main downside is you'd only be limited to ones close to the end of their lease.  People in the first third of their lease are not going to be interested in breaking the lease or paying a lease AND a mortgage.

As to my answer:

If the unit is a highly desired large, view, penthouse, or some other form of specialty unit, then I would market to the entire building with a generic message.  That way, you could hit all three demographics at once, or at least two of the three if you didn't want to send a just listed to the offsite people.

If it's an entry level unit, landlords.  Mid-range unit, owners of smaller units, tenants of smaller units, and landlords.

I would switch up the verbiage created for #1 for both #2 & #3 and market to them ALL! 

Don't leave one stone un-turned! Good luck with your sale, Thomas.

I think #3 might secure you more juice and even if they don't buy that one, you might secure a future buyer. In SoCal, I find owners occupying a weak result; they are comfortable in their fruit salad. # 2 will always try to buy at least .65-.70 /$1.00 making the prospect a tough sell to your sellers who know it is still a Sellers' Market.

I usually send JUST LISTED postcards to the renters.

1. On-site owners

1, 2 and 3 - all of them.

I would go after renters close by
