I'm currently working as a network engineer and would like to start replacing that income with financial freedom in real estate.

Hi Sejin,Are you calculating the rental income based on long term rental or short term rental?

Lastly, if you have a question about a condition on site, have the architect or engineer come out to inspect and issue a report on findings and suggested action plan.If you consistently complete these steps you will be far better protected than the person who has the most elaborate web of entities but performs their duties irresponsibly.

If cash flow is your top priority, Cleveland's reliable rents and predictable income could be a strong contender.

I'm not certain of my debt to income ratio at the moment, but if I try to mortgage out a property to purchase another, does the rental income I anticipate getting from the new purchase factor into the debt to income calculation?

Low Income affordable housing - tend to be rougher on the units, they get a basic 1 tone paint, inexpensive flooring package, no disposal or ice maker or dishwasher - Deep Clean and Safety is my concern. 

especially without being able to increase w2 income very fast?

You’re able to defer taxes by accelerating the depreciation of specific assets which helps reduce your taxable income, thus deferring your tax liability into future years.
