You may want to consider 2 families, especially larger units with 3 bedrooms and more than one bath. 

If you want to cash out refi within six months of buying it, there are plenty of banks that will do the delayed financing option, but your loan amount can be no larger than the purchase price of the property.

At the meetup there was a speaker who was talking about his success to financial independent and when he went through his list of rentals he bought over the years it left me with a lot of questions. 1: Most of his rentals he bought in B+ to A area's in the 300-450k range in Florida.2: His numbers just didnt make sense, one deal he posted it showed literally like a +$5/month cashflow only....So afterwards i started to talk to him more and he mentioned that he is not the type that invest in cashflow, he is a equity investor... intrigued me so i asked more questions and basically he went on to explain to me that he buys properties that need a little bit of work, but have built in equity in the deal, but he has 4 main rules he goes by... 1: If the Roof is greater than 10 years, he always puts a reduction in his offer for a replacement roof.2: If the A/C is older than 5 years, he always puts a reduction in his offer for a replacement a/c.3: If the house is older than 30yrs old, he always puts 10-15k reduction in his offer for a water line replacement.4: He refuses to buy houses with pools....Anyways after a bit of talking he explained to me that he buys larger 300-450k houses, because most investors are educated to not buy them, so there is a lot of room to wiggle on the deals due to lack of competition on offers and most people in that price range are easily able to be purchased with a few % out of the deal to skip agent commisions..Example he gave me, he recently bought a 455k deal for 405k, but the ARV 535k, because he talked them down in needing a new roof, and a/c and offered to pay cash instead of going through an agent if he would drop 4% off the price for that... 

When you start getting up to 6 or more, then it's time to explore a new area (maybe 10+ if you were in a larger market).

As it was stated earlier in your thread gap funding only works if its based on joint venture, percentage or participation of some sort.

How do I know if the market I am looking at is small or larger?

I want to run this for 8 years or so, not life time and use this as sort of insurance income if and when things get rough.

If you are willing to shell out an extra $1k/month to pay it off in 5 years just save the money and put a larger down payment down to lower the payment.

People in the small residential market seem to forget that in the larger multifamily world cap rate is the by far the most important metric, since as you correctly say cash flow is dependent on down payment.
