If people are getting free electricity and water, they tend to be a little less frugal :) .Then check on insurance costs for a MFH and add that to your projections.Finally, talk to your contractors and see what requires permits, what their experience has been in getting them to pass inspections, the timeline and the cost.Factor all of these into the decision to move forward or leave as is - maybe advertise it as a 4/1 with a home office with outside access and get more rent that way.One last point - I hope that the addition you mentioned was done with permits and is reflected on the tax rolls because if not, you may open a can of worms you wish you had not.

Granted, that's of little help if you don't have the cash available but you can use a HELOC on a US property and, even if you don't have access to that, the total price of a Nic property overseas can be less than the downpayment on a US property.

You can also try Expired/Cancelled listings from the past, partner with a Real Estate agent to get access to these.

I have found them online but you might have to search as they're usually accessible only to realtors.

Meanwhile I couldn’t access my money.

However, if you need fast access to funds or have difficulty qualifying for a HELOC, a hard money loan could be a viable alternative, especially if you have a clear plan to refinance quickly.

I would give Schlage a call and see if they can access it remotely from the server.

Lots of good advice above. 98 percent of wholesalers don't even know how to evaluate rehab costs and have no access to get the true ARV and don't care either way, they are just trying to make the biggest spread instead of finding the best win-win scenario.

They could still stay in the house and have access to the entire property. 

Make sure you have proper access to run ARV and make sure you know how to do it.
