Lastly, in areas that are seasonal, operators can consider mid term rental (MTR) for the off season period at a significantly reduced average daily rate.

Our niche is sourcing off-market deals for developers we work with that buy them and build new construction on them.

Cash out refinance, pay off the HELOC and then repeat like the BRRR strategy. 

The new mortgage on the new $340k duplex home which is an FHA loan is going to be a monthly payment of $2800 and we will refi ASAP (the current rate is 6.7%) when rates go down.We have done some nice improvements on the SFR and will be refinishing the wood floors before a renter moves in (July 1) so feeling like it's a great opportunity for the right long term renter and we plan to screen prospective tenants well.We are taking a $20k HELOC on the SFR for the downpayment and plan to pay that off within 12-18 months.

I've decided, starting off, that I'd like to try renting apartments in my current market (Jacksonville, Florida) then furnishing them and offering them to traveling professionals on AirBNB and/or furnished finder. 

An ADU is an Accessory Dwelling Unit -- specifically, a garage or other structure converted into a living space like a studio apartment.Houses can have one ADU and small multifamily property can have two ADUs (and more under certain circumstances).Here's an example deal, one I was exploring with a client recently:https://www.redfin.com/CA/Los-Angeles/624-N-Evergreen-Ave-90...This fourplex has two large garages, each of which can be converted into a studio apartment collecting $1600/month in rent (with plenty of off-street parking still available for tenants).

Now this number will change if the person pays off early, etc.
