Ultimately I would like to invest in more rental properties for "passive income" 

many licensed institutions offer the same exact product and better terms most of the time then private money still being no income no doc and welcoming first time investors .

Time is on your side my friend no need to rush the process and get levered adding tons of risk at such a young age with little income. 

so most people will have to be as leveraged as possible to scale (at the beginning). as in, keep your LTV high and focus on buying 'as much' ($$) RE as possible. this is if you're doing a pretty run of the mill REI strategy like buy and hold. i came across an interesting guideline once: if you could sell today and net 7x+ your annual true net cashflow, you should cash-out/refi, or sell/1031. think of it this way: if your portfolio in a year is worth 1m market value, and you owe 600k, and have a lender that will do a portfolio loan at 80% ltv, you could cashout refi and get 200k to play with (minus closing costs). when you compare the now-lower cashflow from the existing portfolio (higher LTV & maybe different rate), to what you can do with 200k cash, THAT'S where it gets fun. maybe you lose 1k/mo in cashflow on the original portfolio (literally just made up a number, idk), but you can gain 2500/mo in cashflow with that 200k.. then doing the cashout/refi earned you a net increase in your monthly profit of 1500/mo, plus you're getting debt paydown and appreciation on "more" real estate, probably getting bigger tax benefits, etc.

I want to be a stay at home mom and plan to get back out in 3.5 years So I need to make the best of the double income currently. 10k a month in cashflow from would be great, currently at about 3k.

)- I'm wanting to open a HYSA for holding the two deposits and then a checking account for the house as a whole for repairs and income collection etc...

Can I qualify for this purchase using my husband's income, even though he will remain in British Columbia while I relocate first with my kid to our new property?

Those that respond “$0” or something ridiculous, you can request income documentation from them to justify.Don’t be afraid to share with them how much your property taxes & Insurance increased and that YOU cannot afford to absorb them.ALWAYS get an increase or something of value annually or tenants will start thinking they should never have an increase, making future increases that much more difficult to negotiate.

They will pay high prices to meet needs that are not income producing - they are shopping for a different product that is provided from the same stock that our income properties come from.2. having deep enough knowledge of the neighborhoods to allow us to recognize a good deal takes a lot of time.

I recommend you do this annually to adjust for utility increases and other variables.
