Every landlord has a story like this -- my personal favorite variations are when the property was last used as a drug house and/or bordello.

Once in, communicating frequently on the progress, ensuring they understand what's happening along the way, helping them with administrative things that might come up all will lead to building that long term trusting relationship. 

Then go to legal notices.For those that are published Administration and the Appointment (for the PR) phase as started.

I would be leery about buying property in another country where crime, corruption, drugs and general mischief is rampant. 

On a side note, what about using the "I think my tenants are using/doing drugs in my house" card?

Turnkey providers should have a system in place to allow for modest revenue generation and developing relationships with contractors/vendors to provide those services at their cost with a small administrative fee.

It will also limit your access to financing and may increase some other administrative chores.Using LLC is an excellent tool for asset protection.

Anyway, several administrative things you can do (no particular order):Send appraiser before pics Provide rehab list of work doneRun your own comps and let the appraiser know where you think the value should beBe present for appraisal and show work doneGet house professionally cleaned (someone who does this for a living, not tenants). 

The  benefits of the SOLO401K are the much higher contribution limits, and the fact that you can be your own 'administrator' (not sure if that is the correct term) and that IF you want to borrow non-recourse money there is next to no paperwork, or tax, involved compared to the SDIRA. 

Compared to an IRA, Solo 401k contributions limits are roughly ten times higher.There is no custodial requirement for the 401k.You don't need the additional expense and administration of an LLC to have checkbook control.There is a built in-Roth component whereas IRAs are either traditional or Roth, not both.A spouse can also participate in the same Solo 401k plan.The Solo 401k has additional tax benefits over an IRA when investing into real estate using leverage.The penalties for prohibited transactions are less severe.
