After this waiting period of 15 months, you will have 150k in savings that you spent NO effort saving or earning.At this point, you should have about 32 units in your possession.

If you do nothing, they will eventually take possession of the house.

If it's a good borrower, you might do a deal, possession prior to closing and get past that seasoning issue.

Interesting...In my area my cost ranges from $100-$150 for filing all necessary paperwork with the courts & Sherriff service to serve the tenants and approximately 30-45 days until I get possession.

If they sign a lease on that date and pay the rent, they get possession.

Can I go talk to the current occupant or start eviction proceedings before officially gaining possession? 

Did the HOA challenge your ownership/right of possession?

Worry about profit on the next deals using all that knowledge you now possess. 

Will you have possession- right to market or auction it?

I was able to take possession the day after close, even though deed recording was delayed another 1.5 weeks due to holidays and backups at the county.
