I had forgotten that I meant to suggest some changes that I thought could really improve the user experience when using some of these calculators. 

., As a suggestion, there are some expenses you may want to consider, outside of PITI and little maintenance/fixes you're pulling out (i.e. vacancy and capital expenditures).

., which suggest and advise me to get a referral. 

Do you suggest it or advise keeping to the professional websites?

Tenant and SFH resale do not go hand in hand.Your best option is to set it up now for tenants as I suggest and then do another reno to upgrade for sale.....possibly stone, hardwood and tile to maximise profits when you sell assuming they are appropriate for your market.

@Mark Shelstad thanks for the suggestion.

I would also strongly suggest that if they don't take care of things, I won't be renewing their lease.

Thank you for the suggestion, I haven't known *what* to search for !!

If they don't fund it on the initial pass, they may suggest a Phase I and eventually a Phase II, but without the initial survey, they will not do the loan. 

Nice job, certainly not what I would suggest, but I’m glad that worked out for you.
