I use Stessa to self manage 8 properties.

@Gary Abrams A cloud based solution would work really well in your scenario of having other family logging in and helping with management. 

I am licensed agent but work for an investor doing grounds management.

Can anyone suggest and agent or property manager that can help me with this?

Negligent forest management, drug addicts, or illegals? 

Using a HELOC or home equity loan on your personal home could be a good option, especially if you can secure a low interest rate and manageable terms.

The loan is with you, not with your tenant, so none of that means anything to them - in fact because you live in one unit and it's under 4, if you were self-managing you don't even have to abide by fair housing laws (at least on the federal level). 

These homes were built in 2016/17 and I've managed/maintained them myself.

It would be far better for you to join NARPM - National Association of Residential Property Managers SE Virginia Chapter and join as an affiliate. 

Not only do we find the housing market to be a little more manageable, but a lot of people travel there year round.
