thanks or explaining the "bhk" - i had no idea what that was until the end of the post, then had to re-read the post again.
For starters, you are overall in a very good financial position and I don't think you need to be as concerned about money per se as you seem to be. You seem to be fairly young (early 30s?) with $400k in investments and a lot in real estate. That's a pretty enviable position to start from. Plus, you were able to save $50k in 2014 - that's a huge chunk of change.
However, it seems that the real source of your apprehension isn't how much you have, but what you have an how money is allocated. Your husband believes that he should always provide for his parents health and care, and you are less certain about that. how come? Are his parents financially stable themselves? If so maybe you could reach an agreement that you will serve as 'backstop' in case of extraordinary expenses, but his parents should be responsible for paying for their own insurance (if they can). His heart is in the right place and it may very well be a cultural thing at work here, but you and your husband need to come up with a plan that is workable for both of you.
also, you seem nervous about all the properties that you own. Without knowing a great deal aobut the individual markets and properties, it's impossible to say whether these are good, great, or poor investments, and whether you should sell of keep these properties. However, are your properties cash-flow positive? Does being a landlord cause both of you a lot of stress or do you both enjoy it? If you don't mind the landlording and you are making >6%/year after factoring in depreciation and tax benefits, then by all means thank your lucky stars you have such a great portfolio. But if neither of you likes being a landlord (and it sounds like you are paying contractors to do most of the work), then both of you should consider slowly divesting and selling off the properties, and putting all of that money either into an index fund or an REIT.
With "550k in properties" you could have $1M invested by the end of this year, and it would involve almost no work at all.
Finally, you are worried about not saving anything in taxable accounts in 2015. If you are maxing out your RESP, TFSA and RRSP for 2015 then you will still be doing very well. Whether you should be saving in taxable accounts as well has a lot to do with whether you will need that money earlier or not. Since you have rental properties that will provide you with some income if/when you decide to retire early or take maternity leave.
hope that helps. You are doing well - but it isn't how well you are doing that worries you, it's how you are doing it.
