I think it's fair to say that conventional loans are always cheaper in the long run but on the flip side if you can save 5-10% down payment you could buy more properties and increase your cash flow quicker. 

It'd make more sense to just take the straight line depreciation in this case.With the value increase selling is probably the best way to go if they need the money.

Will you increase the value of the property that cost 325k cash?

Lots of new housing units came to market, increasing supply and thus lowering demand.

You’ll get your feet wet landlording have a low down payment and be able to increase your savings dramatically.

So i have a question , I cant think of refinancing my property because if i do , I will have money in my hands but the debt will just increase and increase,  and therefore I will never get out of debt.

Aside from repairs, what else would you do to increase the value?

Here's what my thinking is:Combining the loans in a new 15 year gives me 850/mo increased cash-flow (because they're all at different terms/rates)  YES, it creates a new 15 year loan, but it also frees up a property (#3 above) that I wanted to establish a LOC on to buy additional properties.  

https://www.biggerpockets.com/calculators/shared/2...i think 225 might be a bit low for an offer, so i was thinking offering 285 and increasing the rent a bit. also i figure the closing cost might be higher as this is not a residential loan. 

During the last correction we saw rents go up not down as more people choose rent over ownership the demand for rentals increased.
