Most if not all brokers will come in .25-.75% lower on comparable products.

To determine if you are overpaying for the property I'd suggest looking at other properties that are similar to yours that have also recently sold and comparing them to the property you want to buy.

Numbers look great compared to my market.

Is the price based on the numbers it generates as an AirBnB or market price compared to the houses around it?

If you are self-employed or own a small business - you will be eligible for a truly self-directed Solo 401k plan, which is exempt from UBIT on leveraged real estate, has contribution limit nearly 10X higher compared to an IRA and number of other benefits. 

I have a few follow up questions:1) It sounds like you're saying, if the seller gives the 90 day notice to the tenant so we can occupy that half of the duplex, we can close approximately 35 days after that and be in a 60 day window and satisfy the VA loan requirement? 

Purchase a duplex in San Diego and live in one unit - PROS: essentially get help paying my mortgage via rental income, proximity to rental property, maximizing FHA loan on a more expensive property (maximizing my down payment in a low interest rt environment) CONS: The market is so unbelievably expensive and rents are not comparatively high enough to really make most moves profitable, high Debt to Income ratio thereby limiting my ability to purchase again2.

Stop people you see actively working Ask friends, family, social media (FB, LinkedIn, etc.)Go to Home Depot EARLY (6 AM) and see who is there getting a jump on the dayAlways provide people with a clear punchiest and get multiple bids so you can compare apples to apples. 

@Alex GoncharovReally depends on the local market, type of property, target tenant, rent amount compared to ave market, etc.So, not something I can answer for another city.

There are some extremely supply constrained markets where the national average over decades won't compare.
