Realty Juggler is $99 a nyear.

I love Brivity - it's user-friendly and you can add as much as you want or keep it simple.

LionDesk is pretty good and low cost at $25/month.  See review here: http://realtytechnews.com/liondesk-review-real-estate-crm-offers-value/

Wise agent, happy grasshopper, Google, Microsoft Outlook, Liondesk for Realtors. Top of Mind for lenders.  Check out this article also.

I'd lean towards one which understand you are a working real estate agent. Many of the CRM's mentioned are for the general business person. Nothing wrong with that but if you want letters, flyers, email campaigns, etc geared for Realtors and/or seller/buyers make sure you invest in a Realtor/Agent based CRM. If you want to know where you need to be next week then use outlook or google's suite of tools. I've got my wife and busines partner all sharing a Google Calendar. That way my wife can see my week and plan accordingly and enter/invite me to certain events. 

Lots of great answers already.

Excel

There are tons all claim more than they do. After 12 years and different CRMs, I am back to iPhone. 

You likely have come to the right place for many(and good) responses.  Good luck in your search -- there is a lot of talent/experience in the AR membership.

Lisa, 

You have great suggestions, we made our own. A

HubSpot is very basic - and free.

Mine is integrated with my website. There are some very inexpensive choices listed in the thread.

You've received some good answers here... are you looking for basic or for cheap?

All and every email apps are by themselves basic CRM apps regardless of the one you use. If you use Outlook from the MS-Office ecosystem, you already have one of the best built-in CRM app you can get without going third-party or add-on.

At no additional cost, I should add...

You have many great suggestions here.

There are MANY free versions of crms provided by major companies. 

These free versions come with limited features or restricted database size.

OUTLOOK for some agents is all they need.

Sugar, Hubspot and BellaRuby are three with FREE versions.

Realty Juggler and WiseAgent are excellent low cost providers.

However, it your business is intent on success, you really need to dig deep into providers like Hubspot, bombbomb and Talkfusion.

Very basic sounds like someone in possession of counter-intentions.

Make certain your CRM supports your business plan, and take care to NOT make your business conform to the limits of your CRM.

 Need more information. Basic meaning low price, or basic meaning very few features, or basic meaning easy to use? 

Outlook is very basic and cheap.

I use Lion Desk after a lot of research, it is very basic and very easy to use, mobile device friendly, has few follow up campaigns and ability to track your communication, extra for video. If you decide to try, i'd be happy to send you a code as a member for a discount. ( basic 25$/m but you'll end up with much much  less)

Basic that will do everything you need - Outlook!  I've used it for more than 15 years and it does all I need it to do.

So many choices, such variance in price and features. Read the article Gary Meek suggested.

Lots of good suggestions here.

You have some suggestions. I used Top Producer for many years.

you'll have good answers here.... I've never used or needed a CRM....

Anthony Acosta - ALLATLANTACONDOS.COM nailed this one!

Here is a good read about CRM's. https://zapier.com/learn/crm/what-is-a-crm/

I made my own and it is very simplistic

Depending on your basic needs, Zoho or Reallysimplesystems.com have basic free CRM's.  They have training videos to help you get set up.  I used both and I think if your looking for simple they would be a good choice.  They were easy to use and basic features are available.

I agree with Sam Shueh and I also us gmail as well.

Lots of good answers here ... the best one is the one you will actually use.

We use and love RealtyJuggler.com

I think Realty Juggler is the least expensive option that provides decent quality.

Mine is integrated in my website.  Everything is automated... as soon as a perspective lead starts to complete a form, the lead is captured.  Then an automatic email campaign starts.  There is also Ixact Contact which is relatively inexpensive and a good CRM.

Good luck

What great answers are here

Great answers are here. 

 I have been hearing great things about LionDesk and will give their 30 day free test drive a spin in January.

RealtyJuggler is only $99 per year and they have amazing customer support too! It is very robust however, very simple to learn to use. DO not use Top Producer. And you don't need any expensive ones either. 

I think the most basic is Excel.
