Im looking for good areas to buy a Multifamily property to utilize the house hack strategy, then start to buy up SFHs.

I think it's worth easily $200k I owe $125k. my 4unit has separate utilities I only pay garbage.

I would look to utilize your own boilerplate for the new lease and avoid having to modify the current lease if the expiration is near.

BRRRR method utilizes the equity "trapped" in the property.

The top floor, with access to the garage will generate $2,600/m + utilities and the suite will generate $1,600 + utilities.$4,200 total income-$500/ property tax-$200/m insurance-$150/m maintenance-$100/m city utilities (water/sewer)-$210/m 5% vacancy (even 5% is overkill)-$2,500/m mortgage ($700k @ 2%)=$540/m cashflow - Even if you wanted to have a property manager at 10% the property would still be cashflow positive.This property only generates 0.47% of the purchase price per month (nowhere near the 1% rule) but still cashflows. 

This cost an extra $200 and uncovers things like utilities, code violations, etc.

They’re only paying around $750/mo which is well below market and there’s room to increase the rent to at least $1250/mo.what is the best way to handle my first interaction with the current tenants and how to properly ask them to move out?

This will be one of your factors.Another factor is utilities, do you have utilities on the main street, or you will need to spend a lot just to get utilities to your site?

That is why I said to make a column for category that is used to identify rental income, utilities, personal withdrawals, etc..

Because this is a student rental and so is going to utilities included, I was already planning to get a smart thermostat and smart locks.
