So that means you have to come up with another $100K the accumulated interest, points, fees, etc. over the next 4 years.This is just simple math but it leads to the obvious question of...can you do that?

Before you purchase a MF investment, what math do you do to precisely figure out how much money should be spent on renovation costs?

If his asking price has you cash-flowing $100 per door but you want $150, do the math and figure out what the purchase price would have to be to make your numbers work.

So if my math is correct one option for you would be to own say 5 properties using a 25% equity position and 75% debt position on them, and then own the other 3 outright. 

Matt for napkin math first thing I like to do is look at the Median for the whole MSAso lets say KC the median price point for the entire area is 150k.. which is a WAG on my part but I bet its close in reality.I then know that homeowners are buying basically 130k and up and that landlords are buying 120k and below.. and then know that 30k or 40k is the cheapest area of town and will then by LOGIC and default have the worst tenants in the MSA.. now granted there can be some nice folks there but as general rule birds of a feather.And then I know that Higher end properties are going to rent for more.. and then we do know that its a rule of thumb that you must have 3X rent to qualify for a rental in most markets.. so we want our tenant to have enough for rent and enough to live on .So in my mind I would be looking much closer towards the MSA than I would be the cheapest home in an area.

I have been looking for properties that for sale, finding the comps, doing the math and then trying to put in an offer but my offers end up being way lower than the purchase price they are asking for.

thank you,here in my area there are some houses that will go for 20 or 30k cash and that need some cosmetic work which I can do since I'm pretty handy.I was just thinking about buying 1 of those houses with my heloc then repay it back with the rent money since rents are about 700 for a 3bdr 2 baths.I think I did the math right and I would end up with like 150 to 200 positive cash flow and if this works I don't see why it wouldn't work with the 3rd 4th and so on...is this a good idea or is it just me thinking this way is a way yo financial freedom.

I didn’t completely follow your math but I think the rent you quote of $1250-1450 is per side?  

If you as a landlord use cash-on-cash return (CoCR) to assess rental deal quality, do the math to ensure that this deal will yield you the return you require.

Do the math but I’d think you would get a better ROI with the LG addition.
