Instructions For Dynamically Passing Variables

Instructions for Basic Calculator

Some real estate brokers with advanced CMS tools may want the ability to dynamically pass the home loan amount to automatically set calculation defaults on their listing pages. We created an easy-to-integrate simplified calculator which makes it easy to automatically pass loan amount, interest rate and loan term.

Copy the above code into your site & then edit the variables to adjust them. For example, on the basic calculator edit the loan=300000 part to set the loan amount.

If you do not want to dynamically set the loan term or interest rates you would simply drop the associated variables from the iframe embed. So you would copy and paste the associated code from above, but then remove this part: &rate=4.1&years=30

Here are the variables used in the basic calculator.

• rate=[YourVar] the interest rate on the loan, expressed as a percent (APR %)
• years=[YourVar] the term of the loan in years
• price=[YourVar] (in Dollars) the price of the home.
• down=[YourVar] (in Dollars) downpayment, which will automatically be used to calculate the loan amount as the home price less this amount.
• loan=[YourVar] (in Dollars) the loan amount.

You can use the listing price to automatically set the above variables. For example, if a home is priced at $200,000 and you want to make the downpayment be 20% you would then set the URL variables as shown below.

price=[YourVar]&down=0.2*[YourVar]&loan=0.8*[YourVar]

The basic calculator gives an at-a-glance cost of monthly principal and interest payments, but does not include things like PMI, property taxes, home insurance, etc.

Instructions for Advaced Calculators

The advanced calculators use the rate & years variables which are used in the basic calculator, however the loan variable is not used, as the loan amount is automatically calculated based on the homeprice & downpayment variables.

• rate=[YourVar] the interest rate on the loan, expressed as a percent (APR %)
• years=[YourVar] the term of the loan in years
• homeprice=[YourVar] (in Dollars) the price of the home, which is used in part to compute if PMI is needed on the loan.
• downpayment=[YourVar] (in Dollars) downpayment, which will automatically be used to calculate the loan amount as the home price less this amount.
• ptax=[YourVar] (in Dollars) annual property tax assessment.
• insure=[YourVar] (in Dollars) property insurance, which is typically required on financed homes.
• pmi=[YourVar] Property Mortgage Insurance. No matter what is entered, this will automatically be computed as zero if their down payment is 20% or more / if their LTV is below 80%. If they have a lower down payment then this can frequently range from 0.3% to 1.5% depending on the downpayment amount, loan term and other factors.
• closing=[YourVar] (in Dollars) set this to zero if the closing costs are not rolled into the loan.
• monthlyhoa=[YourVar] (in Dollars) the monthly homeowner's association dues

What You Get...

Great Features & Flexibility

All of these calculators are ad-free & keep your visitors on your site to continue the real estate buying process.

In addition to being ad free, these calculators take advantage of Javascript / Jquery capabilities such that the results change on the fly without even needing to click the calculate button — changing between payment scenarios is lightning quick. Put these calculators on your MLS listing pages and homebuyers can calculate their monthly house payments quickly while looking at the property. Agents can take advantage of the mobile friendly design to estimate payments with home buyers on their cell phones without having to install any bulky apps.

Further, the larger calculators include a button in them which allows users to quickly view & print their loan amortization schedules — all without leaving your website.

Works Across Any CMS & Programming Language

The calculators install as an HTML inline frame (or iframe), so they will work with sites that use any sort of CMS (Wordpress, Joomla, Drupal, Blogger, Typepad, MovableType, ExpressionEngine, custom CMS tools & smarty templating, etc.) & sites programmed in any web language (eg: PHP, ASP, ASPX, Coldfusion, Ruby on Rails, Python, etc.). The embed code includes set width and height settings that are easily adjustible if you want to modify the look and feel.

Wordpress

You can insert our calculator into your sidebar or footer by using the built in widget feature. One of the default widgets is Text, allowing you to paste in arbitrary HTML code like our above calculator options. Select your sidebar or footer area, select the text widget option & drop it into that menu, drop our above code into that widget, then click save.

The other option would be to embed it within an HTML page to make a page focsed specifically on offering the calculator. If you embed our calculator inside of a Wordpress post or page, make sure to do either of the following:

• when editing the page or post click on the "text" option (rather than the "visual" option) so you can paste HTML into it
• disable the Wordpress rich text editor
  (checkbox setting at yoursite.com/wp-admin/profile.php then hit save)

Real Estate Agent & Broker Friendly

Some widely known real estate listing aggregation sites like Zillow and Trulia offer free widgets which then link into their large portals, which then outrank REALTORS® in search engines like Google, Bing, and Yahoo! Search on local search queries:

As an independent real estate agent, you most likely work in a relatively small area, whether it's the little town you live in, or the San Antonio metro area, which is small relative to the country. But sites like Zillow and Trulia are accessible to anyone anywhere in the country, including those people who may be moving to your local area.

By including a backlink to its own listings in your city, Zillow is basically horning in on your local search action. And it's not just the link itself, but the text that is linked, which is called anchor text. When this text is optimized, it helps to target specific searches. In this backlink, the optimized anchor text is: "Homes for sale in San Antonio," meaning it's meant to target people searching for that specific item with those specific words.

Our site's content is strictly focused on helping people buy homes — we do not compete against local real estate agents by publishing geo-focused real estate listings.

We can't, don't & won't try to push you down the search page unlike the big guys.

International Friendly

While the full-page & extended calculators include United States (US) based defaults on PMI, taxes & closing costs, the basic calculator was designed to be friendly to all international markets. It does not contain any specific currency units or region-specific features, such that you don't have to worry about US-specific charges in Canada or a Dollar symbol in the UK.

Security & Encryption Come Standard: HTTPS Implementation

Our site uses a Let's Encyrpt security certificate to load our content in a secured manner. This means when you embed our widget codes in your site, they are embedded in a secured manner. Our widgets work in any HTTP or HTTPS website. And, more importantly, you keep your client's information secured!

You're in Great Company

Many REALTORS®, real estate brokers & home builders leverage our calculators to add functionality to their websites, helping them sell more homes.
