Hi Sushil,My firm does portfolio loans, and if you fit the criteria, we may be able to assist.

Any assistance would be greatly appreciated. 

Aside from that the biggest value add areas I see are as follows: Kitchens, Bathrooms, decks/patios (if added), additional rooms/bathsKitchens and bathrooms tend to be the go-to, but all of those can help you get the most bang for your buck. just keep in mind that if the area is already of high quality, then it may not be the best area to spend the money vs something that is blaringly in need of an update.

I have had no luck trying to propose seller financing through realtors for on market listings.Bottom line, either spend some time and/or money marketing direct to seller or networking with investors that have been around for awhile.

@Josh Green is probably the best realtor on these forums to assist you with short term rentals in Tampa.

Is it good idea to do this project spending about 10k now.

I rent STR mostly through airbnb which acts as a rental manager and I have an assistant that I personally hired to flip/clean the units and also on site for renovations.

Quote from @Evan Polaski: @Jay Hinrichs, while I wasn't going to call them MLM, I did attend an Armando Montelongo (A&E's Flip this House from mid 2000's) seminar at a hotel conference room in 2007 or 08, which was the free funnel to spend $1,500 for a three day seminar or $25,000 for an in-person mentorship.I have seen similar promoted with Christina and Tarrek from Flip or Flop more recently.I didn't start realizing how profitable education can be until the last 5 or so years.  

Currently I'm using propstream, I was having some issues getting my account with batchleads set up and their service hasn't really been the best with assistance.

You will have less to invest, but you will spend within your limits.You must maintain control of your finances.
