Howe much term is left on it, do they have any renewal options? 

Reserved the land but then now knowing what to do, gave away the option on 1st

But most of those were multis. 2 were 11 unit properties.

Investment Info:Large multi-family (5+ units) commercial investment investment.

Failure to complete the transaction forfeits the $20,000 option fee. 

That's also an option to temporarily bridge the gap of quitting a full-time job.It's also important to be making enough on your properties so you're cash flowing enough so you can buy more property - sounds like common sense but as mentioned you can always freelance or do something you enjoy part-time to bridge the gap in pay.

I want to make the best ROI using my FHA loan, and want the multi-unit to be move-in ready.Any tips?

I still need to weigh out my options. 

I agree, the Solo 401k is a very attractive option for those who are eligible.

I am looking at these options since both of these may be within the budget for my investment.Please let me know your thoughts ?
