I’m currently unemployed while in school studying anesthesia for the next few years, but receive some tax free income from the VA.

I have signed leases and have years worth of bank statements to prove that I'm bringing in the rents (which I'm also claiming on my tax returns).

If no money invested then you are just studying and plan to invest.If you have given money to someone connected to this land purchase/investment, then you should have some paper with the terms of your purchase.   

I also understand I could rent out a bedroom in my unit, bust just curious if I have to be there or prove I love there i.e. mail?

It is much more practical, less expensive to purchase, more profitable and easier to purchase multi-unit properties than single-family properties and I will argue and prove my statements, any day, should someone like to get into a serious debate vs. some one-like b.s. arguments.Buy 30 single-family properties, pay down the mortgage, retire and you will make a living and barely keep up with inflation..

Then they can contact the parents and let them know they have evidence from security cameras to prove it is them and the owner will be pressing charges for all future vandalism.

an damaged microwave , it smoked from overdraw with running 2 freezers off a unauthorised surge strip outlet on 15 amp an extreme overloads with 6 strip outlets an wires running out door [ many major  fire codes violations] Can the cost on electrician ,that proved the circuits were overloaded   - [an he warned her on nec an fire  codes  an dangers of her overloading outlets, an  the wires going out front door]    on that 15 amp she illegally ran a strip outlet w freezers  an other circuit w 15 plugs on 1 -- be deducted along with the microwave replacement cost since it popped an smoked kicking breaker by her unauthorised freezers?

Once you do this for a year or two and prove you know what you are doing and that it does in fact make his life better you can approach him about seller-financing.

That is not even enough to clear mortgage insurance requirements, so could prove difficult to pull cash out.HELOC is likely not an option either.

HELOCs may be more beneficial if you plan on repaying the loan within a few years.On the other hand, if you think it will take longer than a few years to repay, then it may prove more beneficial to do a cash-out refi at a lower interest rate, fixed, and spread out over a longer-term.Hope this helps,Alex Roter / Loan Advisor
