I have a very simple clause that tenants are required to initial.

Initially I was thinking 20% down and ~3% interest rate would be a reasonable starting point. 

Initially I was creating the listings from my personal FB account, but have recently added a separate FB page for my rental company.

We explained the 50% by saying something like "obviously we expected some surprise findings to come up after purchase and factored that into our initial offer price.

Either way supply the "protect your family from lead in your home" pamphlet and have them sign they received it along with the other required sig/initials both parties are to do. 

That’s the best bet.Thank you Andrew - I understand that various factors influence , I am in the initial stages , So I am looking for general direction . 

I am also interested in the process of building MFH, but have just started the initial research.

The house is brand new so I figure there should be to many issues and the home comes with a warranty 1 year initially.

I initially was convinced by my mom to purchase a single family home as a sound investment.

@Jaime Rossini,  there is a lot of info missing in your post to allow a full assessment but here is how I would look at the situation if I was to buy with a view to house hacking (live in the vacant unit for a couple of years).Regarding the purchase, this is how I would determine how much gap financing I would need.Purchase Price + Closing Costs for purchase and new mortgage + Cost to Upgrade vacant unit - How much can I afford to invest as my own initial equity?
