However this would cause your interest rate to increase.  

Also, can't I also just issue a 60 day notice to increase rent by $200 or so.

How does everyone handle rent increases with new home purchase, with existing tenants?

I think i need to increase the volume of letters im sending each week.Thank you for the feedback it very much appreciated.

I've also thought about reaching out to one of these major portfolio lenders and putting everything on more fixed long-term debt to increase my cash flow, but I like the idea of paying everything off in 15 years. 

Since I will be moving in 2 years, I'm already planning on increasing the value of my primary residence through forced appreciation and hopefully rent it out over what I'm paying monthly for mortgage payments.I'm exploring the idea of using home equity loans and HELOCs to pay for my next house, but I'm interested in hearing what methods other military members have had success with.

The downstairs is a small grocery bringing in $1000 per month with a scheduled $100 increase each year until it reaches $1300.

Now this was two years ago, and the rent has gone up to $1250 with 2 of the 3 students staying with the house and splitting the rent even with the price increase.

Because once you stabilize the property, you will have created massive equity and drastically increased the cash flow.It takes anywhere from 6 months to 24 months to stabilize a property.

You need to figure out what the market rate is, and for sure with every vacancy increase to the market rent rate.
