I have ideas of the values, but nothing based on anything concrete.If I take out a construction loan, how do I pay for the construction loan during the process? 

You won't run into too many with the quality housing, but there might be a few good Sec 8 homes that you get a good deal on and you want to be prepared.Otherwise, pay special attention to the finishes you use as the quality of finishes can leverage an extra 10-20k in appraised value which can get you the financing/refi that you need.Happy to connect and help where I can!

I live in Miami Florida and I pay over $3 per square foot in rent with some going as high as $5.

If you're unwilling to charge a common fee, I wonder how you're going to handle a problematic tenant who is late on rent or responsible for paying the plumber to remove a kid's underwear from a clogged toilet.How will you conduct a credit/criminal screening without an electronic application?

The property was occupied (still is) with 1 tenant that I am now having the exhausting pleasure of evicting. 2yrs later, said tenant continues to try every angle to delay the court granted Marshall’s execution.The “2nd” floor was poorly renovated (bad contractors), new tenant moved in and a year later, another eviction process has started as they lost their job and refuse to move or pay.Stuck with a very large mortgage bill (that I am paying), utilities and making small repairs to keep the property up also noting the casual 311 complaints from both tenants. 

Set aside a big pile of cash or rely on a line of credit you won't be using.The oversimplified insurance concept is to pay a small premium to cover a large loss.

Section 8 provides consistent pay and the tenants have to uphold the standard put forth by SECTION 8 to maintain their voucher. 

I am scared to pay for the lack of interest. 

Imagine you make $100k and you are affected by 3 tax brackets.0-33k =-33K 0%33,001-66k 10%66,001 - 100k 20%You can take $100k in deductions this year and pay zero taxes, for one year and then $10,100 for for 2 years  ($20,200 total)You can take 67k in deductions this year and pay zero taxes for a year, take 33k the second year and pay $6,800 year two and $10,100 year 3. ($16,900 total)You can take 33k each year and pay $3,300 in taxes all 3 years. ($9,900 total)Obviously this is simplified but unless you expect to make much less and be in a lower tax bracket in the future those deductions could come in handy.

@Nadir M. you would show 100% of whatever you collected on behalf of an owner.Of course, if tenant pays via credit card, you would NOT include the credit card fees, because you did not receive them.From the funds in your OPERATING account, you would pay any expenses on behalf of the owner, including your management fees - which you woul transfer to your PMC account.Owner will be paid from Operating account.Your vendors (office expenses, auto, etc) would be paid from your PMC account.Year end, you are require by IRS to send a 1099 with GROSS amount collected on behalf of owner.
