But, I'll leave the implied warning at that and address your actual question. 

In comparison vacancies in multifamily are easier to absorb due to its scale.A 30 unit multifamily @ 1.5 mil implies you’re buying at 50K a door.

If they are net, then a 2x multiple would imply your $50k will turn into $100k deposited in your bank, but not net of your taxes.Multiple is the sum of all distributions received divided my initial investment amount.  

FHA (FHA implies Owner occupied) will finance at up to 96.5% LTV, but there is an inverse relationship between LTV and cash flow (higher LTV = lower cash flow, lower LTV equals higher cash flow).With $150K and reserving $15K for closing and reserves would give $135K.

If you plan on holding forever, you can very likely be spending large sums of money every 10-15 years for kitchen and bath remodels, all new flooring, etc.Lastly, a 10% vacancy implies you will be down about 6 weeks after each 12 month lease.  

You can get it fully restored to use again by refi'ing the first home out of a VA loan and then applying for a one-time reinstatement (I just did this, so yes, it is possible), but its just as the name implies-'one time'-so if you go this route and buy a second home after restoring your full entitlement you'll have to 'dispose' i.e. sell the home(s) to use it again for the third one.  

In particular, we are talking about the implied warranty of habitability.

From there, your vacancy implies a turnover with one month down every 2 years, roughly.  

What I was implying was that I would possibly avoid setting up a LLC with the contractor (if they are putting no skin in the game and you have no previous working relationship).

A "laundry area" would imply more then a space, it does imply hookup's.
