The reason you would hire a licensed professional is to assist with you not gettting SCAMMED and help you with negotiating prices and terms...based upon State Law. 

I use $2500 to pay expenses and save what's left in a fund for repairs etc...So I can count on approx 5K/month in gross income. 

They are patient and able to talk me through any plans of repairs or maintenance.

Rental income is subject to tax, but it is also possible to deduct many costs related to owning and maintaining rental property, including property management fees, repairs, and mortgage interest payments.Additionally, for those investors holding properties in Germany for the long-term, the country's capital gains tax law is attractive.

This can cover unexpected vacancies or repairs.

I am invested in a small multi family in TX and the management was not able to fill the property and do repairs and the income has dwindled badly.

You will have holding costs along the way with repairs, maintenance, taxes, etc.

We estimate the project will take less than 3 months to complete.I’m exploring alternative short-term financing solutions and would appreciate any advice or recommendations on options that might work well for this type of project.Thank you in advance for your insights and assistance!

I just go in at the first of every month and code each line item to the corresponding property and note what the expense was for (Repair, HOA Fee, Mortgage payment, etc).

It's a good practice to overestimate costs and underestimate after-repair values (ARV) to keep your expectations realistic.
