The existing rent roll was $20,000/mo. at purchase, and we have since already increased it with some lease renewals.

My issue is that I am currently at 10 house loans with Fannie Mae, but selling this house will drop me down to 9, so I should have room for another golden ticket mortgage spot.Now I want to buy two houses and tactically it would be advantageous for me to use a DSCR Loan for the first house because its an existing property, and the the second house its a new construction tract home that will only take conventional financing.Under Fannie/Freddie rules would lender view the DSCR as "Loan Number 10", and I wouldn't be able to get a Fannie Mae conventional mortgage? 

If you buy a property with occupants, you inherit any existing leases on closing day.  

You will not get a second loan based on a value of an ADU that does not exist. 

Because it sure doesn't exist today.

If you decide a duplex house hack could be successful in your area but you can't find one, could you try converting an existing single family home?

Plenty of folks are fighting over existing inventory, but I'd love to hear if anyone has experience building them.

Existing construction, particularly in Cape Coral and the surrounding area, can often offer stronger annualized returns, and that is still accounting for ongoing maintenance.I am obviously partial to this area, but there are very few opportunities across the US right now that offer the growth potential we're seeing in multiple Florida markets.

There are definitely some towns to stay away from at the moment, but there are a few towns that wouldn’t be able to stop something that has been part of their existence for decades.

Immediate goals basically are-find other markets than so cal; and-figure out commerical financing, preferably use leverage of existing assets to acquire new ones rather than cough up tons of cash (ive heard this can be done but never tried it, looking into helocs now)looking forward to contributing as much as i can and learning from you all!
