Unable to access relationship Laravel HasManyThrough

I have 5 models, 2 are pivot/intermediary models.

Tenant,Landlord,Property,LandlordProperty,TenantProperty

Landlord & Tenant need to be accessible both from within the Property model and also exclusively.

Currently, I am unable to access the Landlord model from Property, it simply returns no data.

Tables:

Property table:

------------------------
|       id|   propTitle|
------------------------
|        1|  Property 1|

Landlord table:

Tenant table:

TenantProperty table:

-----------------------------------------------------------------
|       id|   tenant_id|   property_id|contractStart| contractEnd
-----------------------------------------------------------------
|        1|           1|             2|   01-01-1970|  01-01-1971
-----------------------------------------------------------------
|        2|           2|             1|   01-01-1970|  01-01-1971

LandlordProperty table:

-----------------------------------------------------------------

-----------------------------------------------------------------
|        1|           1|             1|   01-01-1970|  01-01-1970
-----------------------------------------------------------------
|        2|           2|             2|   01-01-1973|  01-01-1973

Models:

class Landlord extends TenantModel {
    public function properties(){
        return $this->hasManyThrough('App\Property', 'App\LandlordProperty',
            'property_id', 'id', 'id');
    }
}

class Tenant extends TenantModel {
    public function properties()
    {
        return $this->hasManyThrough(
            'App\Property', 'App\TenantProperty',
            'property_id', 'id', 'id');
    }
}

class Property extends TenantModel {
    public function landlords()
    {
        return $this->hasManyThrough(
            'App\Landlord', 'App\LandlordProperty',
             'landlord_id', 'id', 'landlord_id');
    }

    public function getLandlordAttribute()
    {
        return $this->landlords->first();
    }

    public function tenant()
    {
        return $this->hasManyThrough(
            'App\Tenant', 'App\TenantProperty',
             'tenant_id', 'id', 'property_id');
    }
}

class TenantProperty extends TenantModel {
    public function tenant() {
        return $this->belongsTo('App\Tenant');
    }

    public function property(){
        return $this->belongsTo('App\Property');
    }
}

class LandlordProperty extends TenantModel {
    public function property(){
        return $this->hasOne('App\Property');
    }

    public function landlord(){
        return $this->hasOne('App\Landlord');
    }
}

The following loop returns no data on $property->landlords and I am unsure why

@foreach ($properties as $property)

    <tr class="clickable-row" data-href="/property/view/">
        <td></td>
        <td></td>
        <td></td>
        <td> </td>
        @php

            echo '<pre>' . var_export($property->landlords, true) . '</pre>';
        @endphp
        <td>
        @php
            if($property->status == 1){
                echo "<b style='color: green;'>Active</b>";
            }else{
                echo "<b style='color: red;'>Disabled</b>";
            }
        @endphp
        </td>
        <td></td>
    </tr>
@endforeach
