Isaac , this is a very ambitious project my friend.I would start with Bildwise ,they have extensive experience in this market,and contractors they use all the time,which gives them consistency.They can probably ball park it for you first and then do a detailed sow if you choose .Disclaimer :I have no affiliation with BildwisePlease keep us in the loop with progress 

What are the details of this deal?

They provide no details or insights in why they are not able to find a tenant.

*HOAs usually cover lawn care, sprinklers, lawn watering, siding and exterior care, insurance, and more                *This covers most of the exterior line items that you would otherwise have to address in a single family home.

Also, YOU need to be the person who makes the monthly mortgage payment, or the seller needs to provide you with online portal access to the mortgage lender's website or have statements sent to your address / email - so that you can make sure that it is being paid.

Contact me for further details.

Working smart means not avoiding the things that are within your power to address today.MultitaskingPeople love to claim they are master multitaskers.

I would get the email address for the case worker and email them.

But now I know how to figure out what can be built on site in detail and get a good rough estimate on costs in a matter of hours.

posting the address might get you some interest
