Land purchase of a 0.11 acre, R-2 lot was used as downpayment for a conventional mortgage.

You can get a conventional loan for 3.5% down or maybe even 3% down depending on your finances. 

@Leah C Ogren you can get a conventional or FHA renovation refi where the hole in the wall wouldn’t necessarily hurt you.

However, I did want to know for when the time comes, a bit more about conventional loans in CT.

We own 3 properties:3 unit, ( 3 2BR, 1 BA units) purchased in July 2019 for 657k. 3.75% conventional, 30 year fixed, 5% down.

@Michael Lightwood I believe the best way to get started is by purchasing a house hack in which you rent out rooms to cover the mortgage or rent out a side or two of a duplex/triplex, using a primary residence loan 3-5% down conventional.

On the other hand, you can use conventional financing on the duplexes. 

Conventional FNMA or FHMLC is maxed at 75% for an investment property.

I am doing a 30 year conventional.  

Both are important.If you see a negative net migration over the last 10 years, it's probably a pass.If you see a positive net 10-year migration, but a decelerating rate of year-over-year in recent years, that's a sign that it's a maturing community, and till probably not have the same explosive growth it had previously had.Now, ALL that said, if you're talking about net-migration numbers in the single-digit thousands, you're probably looking at too small of a slice of the MSA.
