My husband and I are interested in investing in rental real estate (initially buy and hold) in order to supplement our retirement (which is about 20 years from now). 

On the flip side, if you put systems in place for effective management and screen your tenants thoroughly, you can very well supplement your current income with consistent cashflow. 

This might not be right question to ask given how situation specific it is, but what would be a cash flow difference to aim for with respect to how much I could lease the property for and then sublease it?

I am aiming for a refinance but without that tenant, appraisal will be low.What is the average vacancy rate for a shop in a commercial shopping strip?

Anyway, YOUR Offer should aim to get you that 30%+ discount you'll want/need whether you're Flipping or BRRRRing!

My brother wanted to sell it, but I decided to start an S corporation and rent out both sides so we could supplement our incomes.

Besides, if you want to do flips, you should really start spending a lot of time familiarizing yourself with the products available to you and figuring out what you can afford to do - that way you'll know what kind of flip to aim for.  

I will do some of that but after listening to some BP podcasts and doing some general Googling I feel that I can supplement my income nicely in the flip or rental game.

So assuming we can't raise this number....knowing that 75% LTV puts us at ~$122k....and aiming for $0 out of pocket, I would have had to buy this property at $90k. 

I have been able to save about $20k and am ready to purchase something that will supplement our monthly income without taking too much time away from our current jobs.
