What's your main objective that you are trying to achieve? 

Beginner finance teaches us that the riskier an investment is the higher returns the investment should achieve.

On a long hold, you will definitely achieve your goal.  

Perhaps the appraisal comes in higher and this target is achieved even at 65% LTV. 6.

Does keeping the house as a rental help you achieve those goals? 

Our goal is to achieve a million in cash flow by 30.

As my advice would be to look at what you want to achieve, is it higher cashflow?

Lastly, set deadlines to monitor progress.Once you've established your achievable goals, the next step is to assemble a reliable team in your target market to support your success.

And if a group is out there projecting that 20% IRRs are still achievable for a typical value-add play, I get very suspicious, and ask for a lot of "projections vs actuals" on current deals to confirm their assumptions.

Rents greater than the PITI payment and if you can focus on 2-4 units the multiple doors help achieve that goal.On another note keep in mind Mobile/manufactured can be tough to refinance some lenders do not fund on them.
