For example, I have my house, am building a legal JADU, but later down the road I decide to rent my entire house and buy another primary residence.

For these non-paying tenants, will landlords be able to collect rent from them later?  

I wanted to share the numbers and want to make sense if it's a good deal for us according to what we are looking for.Price: $450k (agent said that we can get it down to $420k)2 Units (1 bedroom in each unit)Mortgage with 3 year fixed comes up to around $2.3kInsurance and tax is roughly $400Rent per unit is $1.4k so if we move out then total rent comes up to $2.8kThere's a detached ADU (garage) that can give us another $100-$150 if we rent it for storage and there's a scope of converting it into another unit later on.So currently rough calculation says that it can cashflow up to $300 per month.

This means there's not really an incentive to buy another house to be able to still be established here in Italy, since it's entirely possible she will inherit it later. 

Consider all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.

For sure get an investment property first which is affordable (out of state), then later, buying your primary home will be even easier with lenders.

This is all a psychological game to just get the user to cave in and think later.

Will cover porch later during the rainy season.  

For instance, in Sec. 401(a)(9)(C) it says:...The term “required beginning date” means April 1 of the calendar year following the later of—(I) the calendar year in which the employee attains the applicable age...Example 3.

We can later sell or refinance the loan to cash out of the deal.
