@Fahadbin Alam Listen to James above, he is a great realtor and knows his stuff with house hacking and lending!
Congrats on getting your 1st House Hack!
I can definitely answer your question, here's what I did with real examples.
1st House Hack - 4 unit - I purchased this multifamily in August 2017 with 7% down (couldn't do 3.5% down because of the FHA self-sufficiency test).
2nd House Hack - 1 unit (single family house with mother-in-law apartment) - I purchased this property in the summer of 2018 with a 5% conventional loan (a little over a year later), and I was able to move out of my unit in the 1st House Hack and into the basement apartment of this house hack. I didn't have change the loan or anything.
3rd House Hack - 1 unit (single family house with mother-in-law apartment) - I purchased this property in the summer of 2019 with 5% conventional loan (one year later), and I just moved out of the 2nd House Hack, had a renter move into our master bedroom in that property, and moved into the top unit of this property.
4th House Hack - 1 unit (single family bi-level house with mother-in-law apartment) - I purchased this property in the summer of 2020 with 5% conventional loan (one year later), and I just moved out of the 3rd House Hack and rented out the master room, and moved into the master bedroom of this house hack.
Do you see the pattern? All I did was move each year, and I was able to acquire four properties much sooner because each one was my primary residence than if I tried to purchase them as investment properties (minimum 15% for single families).
Also, since the Denver market is very expensive (median price is 500k+), that would be at least 75k down payments for investment properties vs. 25k down payments just to move into the property for one year. That's a huge savings, and I'm in the acquisition phase of my portfolio, so I will do whatever it takes to get more properties here.
Also, I didn't mention that I refinanced the 1st House Hack into a conventional investment property loan, but I had built 25% equity over that time. I'm looking to refinance my 2nd House Hack as well. Sometimes, you can get the benefits of appreciation.
There is definitely risk to putting 5% down payments, but I also bought down the interest rate and paid points to give me the lowest mortgage payment with that down payment to mitigate that risk.
