I would think about paying a higher rent rather than a percentage of the airbnbs. 

Rather, they will use only a percentage, often less than 50%.You also have to be careful comparing floors.  

As your cash flow increases each year then you slowly up your lifestyle but the percentages are still conservative.It's kind of like the difference between someone buying a multi-million dollar house to live in that barely qualifies.

Didn’t know equifax offered this service that’s interesting A small percentage of list source data is not very accurate

If you have owned the property less than 24 months,  the lender will use the value  from either the purchase price or percentage of the appraised value.  

There are companies out there who will manage it for you and give you a percentage.

In order to come up with the approximate 60k (dependant on the percentage) needed for down payment.

If so, what percentage of what?

Here are some of the pros and cons that I see:Pros:Property management costs would be lower over the life of ownership due to proximity of homes in portfolio, low maintenance flooring, siding, etc.You could build them with more robust systems(HVAC, plumbing, etc) knowing they would always house rentersYour portfolio would be concentrated as opposed to spread all over a geographical areaYour exit strategy would be super attractive if you were to sell as a packageQuicker than purchasing and potentially rehabbing an older property, and accumulating them one by oneYou could sell a percentage of them to recoup a portion of your investment, and rent the rest, which should put you with solid equity from the gateCons:Entry costs and length of time from start to first months rental income for constructionFunding the construction, or finding the right lender to fund such a property/developmentKnowing the correct price point of the finished product, or what the community is lackingLocal zoning or possibly being prohibited to build SFH to rentHigher construction costs vs. multifamily(apartments or townhomes)I know there are many other strategies out there, but as one wanting to accumulate a nice rental portfolio, this seems to be a solid approach.

Don’t get over leveraged with short term and/or variable rate loans.
