I have a couple applicants that are married with a newborn baby.

It's guaranteed that at least the baby daddy will live there, possibly an entire additional family.People from some cultures/ countries have no problem putting an entire family into each bedroom.As noted above, it's impossible to prove occupancy.

My fiance got one for the 3 family we live in now and it's been over 12 mos and we had a baby since being here.

Stop babying the thing and take your responsibilities seriously before the dog causes serious trouble.One more reason special rights should be removed from "companion" pets.  

If we set up so that the parent LLC is a member of the "baby" LLC, can funds from the parent LLC be used for the baby LLC?

The other triplex we purchased at $49,500 we are $16K into renovations its yields $2250/mo with a break even of $700/mo, we estimate another $30K will get the house in great condition(windows, account for $15K of that).The $130K property purchased in 2013 now values at $500KThe $49.5K property purchased in 2016 now values at $82KThese are all great comparables because of the cost of acquiring these properties in terms of cash to close are relatively close.In reality, the Toronto renters there quality is A-/B+ or on a scale of 0-100 prob an 88 (both families where the earners work in Engineering or Technology)The Detroit renters their quality ranges from 75-95 where the income earners are Trust Fund Babies(I consider the lowest grade), Medical Resident, Consultant at a Big 4 Accountant Firm, A Law Library Librarian, Marketing Professional, and Electrician.The high cashflow rentals fuel the ability to purchase the rentals in more "desirable" areas.

People invest in their business/company and take care of it like it's their baby and for good reason.  

Just take baby steps and see where it takes you.

You didn't skip over the couple with the baby and take the two "singles" who are doing an apartment share because you didn't want to deal with possible lead paint exposure down the line.

@Rachid B.there are some exceptions to the 2 out of 5 year rule that allows you to get a partial exclusion.Work-related moveHealth-related moveUnforeseeable events such as family death, multiple baby births, etc that caused you to move?
