People promise the world, but until you get in bed with them do you really know if they are all talk or not. 

I think it might help some seasoned landlords answer your question if you share details about your rental like bed/bath count and sq ft.

Is the garage big enough to have a full queen bed in there with some furniture for an extra sleeping area.I would also add the PS5 or maybe a Switch or Wii?

Guy was a true pro knew how to run his bizz.the next year same town Hamilton MT.. terrible no info sheet when you got there so could not figure out wifi..one of those stupid TV systems U cant figure out RoKU i think they call it .. jsut the worse.. then this last year kind of middle of the road furniture was old beds were bad house was clean and that was about it..

If you have four 2-bed/1-bath units with the same appliances, split it four ways and call it a day.

I didn't go over board, but having to buy dining room table, 2 beds and sofa and table for my living room added up and for $50 I was able to delay paying by 6 months interest free.

I would like to split the downstairs unit, currently a 200 sq ft 5 bed 3 bath, into 2 2 bed 2 bath units AND convert the garage to an ADU.

First off, huge props to your dad for building that real estate portfolio over the years 👏🏽 Given the numbers you shared (3.4% fixed mortgage is chef’s kiss), it sounds like a solid property with a lot of upside, especially since you already know the ins and outs and can add value by converting to 3-bed units. 

They always sell for less than 3-bed homes, but rent for close to the same.I run meetups in Northern NJ every month, but I have friends who run some down South.

They teach everything from finance to what mattresses to put into your rentals - so much great information and I was really impressed.
