Learn the math for whatever type of investments you want to make, once you have the math down it is easy to formulate a goal for saving from there.

Allentown/Lehigh Valley: I would call this area the secondary market.

If I run some very rough math on the deal, it seems like your all-in costs for every penny spent are in the low 150s - 150-155.

For secondary heat you could install inexpensive electric baseboards and the tenants would only need to use them when the temp drops below -15 I believe, depends on the heat pumps that you install.

The big issue I see at the moment is that 203K loans disappeared from the secondary market in March and only 2 have come back so there is not a lot of pricing competition at the moment.Originally posted by @Christopher Miller:Thanks.

I’ve got some math to look at.

Back of the napkin math tells me that if I could secure a line, we could buy several (3-5) small rental units and not have to average huge nights/year or income/night numbers to cover both the LOC as well as conventional mortgages on the new properties. 

@Brian Valdivia - Thanks for doing that math.

I'd rather understand the math and the formulas behind the profit margin.

That's a secondary concern.
