You probably also find a huge difference between SFR, Small multi and large multifamily.

Whatever they ask from you as a safety net, do a bit more.

When I run my numbers I round my interest rate and insurance costs up to build in a small safety net. - Next I use a calculator to determine how much money to put down. 

.: I just hired an architect to design and plans submit for ADU in my 8 multi unit to use the tuck under parking.Some people say do not try to be the general contractor as it will take way more time, costly mistakes and will be nearly impossible to manage with current work. best to hire a company that will do it all and cost about $250 per square foot.

Investment Info:Large multi-family (5+ units) buy & hold investment in Tuppers Plains.

Quote from @Michael Johnson: Investment Info:Small multi-family (2-4 units) buy & hold investment.

BUT, the might cause more issues because 550k is already on the small side for a 5+ unit building product. 

I've only really looked at multi-families in the area and am not as familiar with SFH.

Threatening each others' safety is never allowed.
