I will outline my interpretation of what I have read below, in the hopes that someone here will tell me that I am waaay off and my tax liability will be much less.

Failure to provide timely notice of intent to terminate this Lease may subject Tenant to liability or additional Rent...The renter paid a pro-rated rent for the last 3 days of April and May was his 1st full month.I believe both the tenant and I were interpreting the lease as 12 months starting on April 28th, 2018 and going through April 2019. 

My response is based on your interpretation.

If there is any ambiguity in the contract, it would be interpreted in favor of the party who did not draft the contract, I would assume that would be you.

Am I interpreting that correctly?

@Nick Brown  The broker is projecting that if you lease all units to his interpretation of market rates and are at 100% occupancy then it will be equivalent for 17.5% cap. 

Please check your own state's interpretations of this. 

@Dale Miller  FHA, VA and USDA appraisals are far more difficult than for a conventional loan.Appraisal for a conventional loan is looking for the value of the property and to ensure that all major systems are functional - water, sewer, electricity, heating and AC.FHA/VA/USDA does the same, but will also fail for anything that can loosely be interpreted as a health or safety issue. 

You have to show some sort of ability to repay the loan, although I am seeing more lenient interpretations of this rule with new loan programs coming out.  

Also, if i'm reading and interpreting correctly in order to invest in these Opportunity Zones for the tax benefit the money invested MUST come from a capital gain.
